Just a note to say thanks for the quick service - the cable and parts arrived next day and  the picture quality improved. And also for the advice on the phone which saved me buying something it turned out I didn't need. Everything now works perfectly.                            Mark Williams (Oxfordshire)

Ok, just a short testimonial to summarise the service I received.
I ordered all the bits for putting up a new digital TV aerial and required some advice on this.

I received replies to my query emails within hours, not days or weeks(or never) like some. These guys genuinely know their stuff and you can tell by their superb no nonsense website. Sure, they're not the cheapest, but I think we have too much 'cheap' in our country these days. You get what you pay for and that gets you superb service and parts.
Buy with confidence. Absolutely excellent company, too few like this out there any more.
Well done. K Jones (Northampton).

Thanks very much. This kind of service is why good companies (like yourselves) get referred to friends. Regards    G Watson (Dunblane)

I found your site a few days ago, and your info on TV aerials and mounting has helped me solve a persistent problem with poor digital reception from Sandy (Beds).I bought from a  new mast and bracket set - delivered very quickly. All installed yesterday and the problem  is gone. Thanks for the excellent info and service.  K Parry (Cambridge)

I came across your web site from MB21 transmission site link. I must say that if your site  is a representation of your work, then you must be listed as some of the best designer / installers of antenna systems I have ever seen ! I have been going over the information listed at your site and have found it very interesting ! I been in electronic servicing for over 35 years and I'm just amazed at your site. I have spent about 3 days on my off time going over info  on your site. I now have a better understanding of broadcasting in the UK. Living in the  Midwest U.S. our system is different, but the same rules apply, and with our digital switch over coming I already see a host of "junk" being sold as digital ready, or HDTV ready.       So we may start to see what you folks have been dealing with for years. Enough said, congratulations on a very informative and interesting site !!!   Best Regards !!!  

Greg Hammack (USA)

Received my order in record time (considering it's Xmas). All bits there. Even managed to follow instructions. Really useful web site. Cheers Good luck. Dix (Boston)

I am a very satisfied customer ! I phoned-through an order on Monday afternoon - and it arrived Wednesday morning ! The order was well packed, everything that was ordered was included and the materials were of high quality. Accurate interpretation of order - goods   well packed - prompt delivery - high quality parts - and all at a reasonable price.              This Company sets an example that many others would do well to copy. I would certainly recommend Aerials & Television to any one who values good service.     R Hutchins  (Hertfordshire)

Thanks for looking after me, all working OK now !  Mr Perry (Sevenoaks)

Best picture we`ve ever had, thanks a lot. Mr Green (Quedgeley, Gloucs. Off Ridge Hill))

After taking your helpful advice on the Mast Head amp it worked perfectly, thanks very much.   Mr Fowler  (High Green, Sheffield)

I was most impressed with the helpful service and the quality of the products. I now have perfect pictures, a very happy customer. Mr Pinn (Wetherby)

It was a pleasure doing business with you, I`m sure I`ll return for future purchases. Great Website, full of advice. Incidentally many of those living in South Liverpool are on Storeton transmitter (rather than Winter Hill) due to the hills around Woolton. G Partington (Liverpool)

I found you using a web browser and was very impressed by the quality of your service which I found to be polite, knowledgeable and helpful. The products I ordered were dispatched promptly and arrived in very good condition.  A Chaplain (Manchester)

"The content of the aerialsandtv website is the best information resource for aerial installations that I have found online and has allowed me to troubleshoot and solve all of my household TV signal issues as well as buy the correct equipment. As a result I had no  issue in ordering from the company and can confirm that the subsequent service provided  by ATV was extremely helpful and delivery was prompt."  J McCallum (Glasgow)

Back to the top

Required cable, mast, lashing kit and bracket, in order to move my aerial to chimney  height, and at the same time, get rid of my old brown coax. I chose ATV largely because their website gave the impression that they were a professional and trustworthy company. Someone had gone to considerable trouble to publish that knowledge, a most informative and entertaining collection of data. I was not to be disappointed. I was greeted politely on the phone, and the person at the other end obviously had the time to discuss my options, even though the order value was relatively small. The items were dispatched the following day, and I received them the day after. All items were as I had expected, i.e. high quality. I have no hesitation in recommending ATV to anyone wanting to change/upgrade their aerial installation.  B Wilson (Cumbria)

ATV provided me with an aerial, pole cable, fittings etc. With their excellent advice and competitively priced quality products I was able to get a really improved signal into 5 rooms. I have no reservation in recommending the company to anyone.
Many thanks R Reynolds (Birmingham)

The order arrived promptly and everything was fine apart from the (10ft) mast which had somehow been crushed at one end. As I did not have time to ask for a replacement I decided to use it as it was. I found the person who dealt with the order on the phone both pleasant and helpful and would be happy to recommend your firm to others. I realise that you are not to blame for the condition of the aerial mast. Many thanks J Butler (N/hampton)

"ATV provide a truly expert service and managed to get me decent reception in a very poor area by recommending and supplying exactly the right equipment and advice. Good prices too." Colin Duffy CEO Inet Telecoms ltd (Voipfone)

Your advice and service was first class, the aerial you recommended is performing very well. I had a problem with reception on BBC 1 from Bilsdale this is now cured, also just to let you know that I can still receive film 4. The only problem I encountered was the delivery which took 5 days with numerous phone calls to yourself and the carrier though I am aware that once the goods leave your premises you have little control. Brian Ashton (Darlington)

After looking at the information on your useful website recently, I telephoned ATV to  get some advice on a splitter for my loft aerial and whether I needed an amplifier. Following the advice given I purchased a four way splitter which arrived the very next day. The splitter was good value for money, of a high quality and worked perfectly. I now have three TVs running off my loft aerial (with one spare socket) and each has  very good quality pictures. Thank you ATV for your impartial advice and excellent service.  John Phillips (Devon)

Back to the top

Just to let you know that after your phone advice, the new mast and fittings I purchased have been installed and the aerial is working well on both digital and analogue signals - after a 6 month period of rubbish reception while our chimney was being demolished then rebuilt and the aerial graced the scaffolding pole! Your website has proved an excellent source of informed guidance, and I have undoubtedly saved money by heeding the advice given. Thank you, and by all means add this to your well-deserved testimonials. (S Aitken  Bucks)

We take customer service very seriously, but we also like to hear when our products have helped our customers achieve the desired outcome, not forgetting any info which may be of help to others reading this site. See contact us, or the phone !

An excellent web-site with all the information there to do the job yourself. I live on the outskirts of Brighton, so a firm in Sheffield is not the natural choice, but after a quick search on Google their name popped up. After studying the ATV website at length I was very impressed with their knowledge and the quality and price of their equipment. I placed an order, the goods arrived promptly the next day. I installed the aerial the next morning and  am now receiving Freeview. I now spend most of my time looking up at inferior poor quality installations !  An excellent company to deal with.      Thanks C Gibbs (Brighton)

I spend (too) much time looking at aerial installs as well. My wife constantly reminds me  not to do this this whilst driving, a lesson to all of us with a similar inclination !                          Justin Smith (ATV)

Customer Feedback

I don't do feedback to websites, especially when, having purchased a product, I get an unsolicited mail from, or whoever, saying "rate your recent transaction from.....".

"NO" I think to myself in my best grumpy old man thoughts, "go and insert the Paxo in an appropriate fashion".
You lovely people are different, though. Having lost signal, (we were fine after changeover to digital) I eventually climbed onto the roof from an attic window, convinced all I had to do was remake a broken connection, as we sometimes had an intermittent signal. As I have often found in the past, I was wrong, corrosion meant the aerial was past all hope of rescuing. Whilst I was up there, I took all three aerials down, the other two being an unused VHF 4 element yagi and a 5/8 150Mhzwhip. When I installed the whip originally I had stood on the chimney to do so, no way did I have the nerve to do so again, I'm a pensioner now. So, back indoors to talk to my friend Google, and I found you site. I must say I was delighted I did. Good common sense info and the oft quoted statement that RF is a black art. After a pleasant couple of hours browsing, chuckling & learning, I decided on a log periodic & a roll of cable, which I ordered on a Sunday. We were just about to go out the following Tuesday, (It's great being pensioners!) when the courier arrived, before 9am, with the goods! terrific service! So, up on the roof, easy guesswork alignment of the aerial as the 3dB points are quite far apart, & 100% signal and quality on 3 muxes. (The other 3 are lower power on Mendip at the moment, but still 100% quality)
So, connect everything back to the distribution amp, and.....nothing! It had died. So back to your site for more advice, and bought a variable gain masthead amp. ordered by phone so save on postage, ( I may not be a northener but I can pretend,) and the young lady said "the postman collects in 15 minutes, we may may not get your goods out tonight." Next day the postman knocks (twice) and there is the parcel from you. That is really good service, and dedication above and beyond the call of duty. I shall certainly recommend you to my friends, and use you again when I need related products. Keep up the good work!       (C Greaves   Trowbridge)

I think the lesson here is that using decent cable, decent splitters and proper face plates makes a big difference.  (Dave Jones   Enfield)

It is not unusual to improve your signal by either dispensing with a cheapo wall plate or swapping it for a decent non isolated screened one (Dave`s been quite lucky to get this much improvement though ! ). The isolating caps can negatively affect the signal and a lack of screening can pick up impulse interference.  My advice chimes in with Dave`s, and is to always replace cheapo wall plates, plus any budget splitters or cable. None of them are particularly expensive, so just change them as a matter of course     How to repair a Budget wall plate.

[Link]  Just to say thank you again for the prompt service form ATV. With the help of your excellent and informative website, and the stuff I ordered from you, I have now wired up the downstairs extension for sound and vision.

When the new aerial was fitted last year I asked the install guys (CAI)  [Ohhh. Ohhh.......  I should add here - in best "Have I Got News For You" fashion - alledgedly.........]  for a screened coax face plate (like you sell) but they just fitted a cheap and nasty one, probably because there wasn`t enough depth in the existing pattress (they should have used a spacer plate......). Anyway the signal quality seemed OK so I didn`t really care that much. However every now and then there would be picture break up etc, which I didn`t want with a new aerial. I then replaced the Poundland shop aerial leads with ones from ATV and that seemed to make a difference. The picture still broke up but not as often. My next step, whilst adding DAB points, was to use decent face plates. So I ran some new cabling under the floor and when the installation guys came back to join up the cabling outside I asked them to replace their faceplate with an ATV one and use the spacer which I had bought for the purpose. It could be the cheapo faceplate wasn`t wired up very well (I thought they were professionals ! ) but I now get both better DAB and TV with the screened face plate even though it is split.

I was surprised at how much difference replacing the faceplate made. From the figures I could have split the TV signal at least one more time !

(I have summarised Dave`s results into the table below)

I recently ordered aerial cable, splitters coax plates etc.

Firstly I would like to say that I found the information and guidance notes on your website were extremely helpful and excellent to use to help identify parts required and how to fix correctly, descriptions and pictures being excellent. Whoever designed this did a first class job. I would also like to say the lady that took my call was also helpful with ample knowledge and patience to assist. Finally I would like to say the products were supplied at a competitive price, well packed, dispatched and delivered extremely quickly.  Best regards Keith (Northampton)

Errrr, watch out !  Yesterday I walked into a lamp post (ouch ! ) whilst preoccupied by a crappy Bacofoil installation hanging off the chimney on a house in Bredbury Green (Manchester). Unsurprisingly it was installed on a house owned by a builder, he probably bought the tin foil aerial from Screwfix. Obviously I should have been looking where I was going, but, at the same time, if the aforementioned builder hadn`t parked his van half way onto the bleedin` pavement, I`d not have been walking right up next to the wall where the lamp post was waiting for me...... Anyway, be warned. (8 Apr 2011)

Carlsberg [or Carling for that matter] don't do aerial websites but, if they did, this is exactly what it would be like. Seriously, your site is full of superb information, I'll be ordering very soon !      Paul Harrison (Bristol)                                      (and he did, thanks for that.......)

Thank you for the prompt shipping of the aerial and fixings I ordered. I installed it the next day and we now can receive all the digital Muxes from Winter Hill despite us living in a ditch where everything else is pointing at the local relay on Dog Hill. I thought you might be interested in the method I used to determine the exact direction to Winter Hill from my house. Which is a big help to limit the amount of wafting the aerial left and right once up the ladder, while someone else is watching the signal strength indicator on the STB. Use Google Earth to open up a image that includes the transmitter location and the location where you are trying to receive it from. Using the "ruler tool" of Google earth draw a line between the transmitter to the receiving area.(rough locations are ok at first). Then zoom in on the transmitter and using the ruler tool again move that end of the line to spot   on the transmitter. Then zoom in on the receiving end and using the ruler tool put that end  of the line spot on where the aerial is to be mounted. You now have a picture, that you can save and print, of the exact direction to the transmitter. Also the Google ruler tool tells you the exact distance between receiver and transmitter. As a last bonus feature, If, as in my case, there is high ground close by between my house and the main transmitter you can  put the cursor on the house and Google earth shows its elevation above sea level, (add height of house and pole) then moving the cursor along the line you can locate the highest point and it's elevation between the receiver and the transmitter. Drawing a new line  between my house and the high point, gives the distance, from all this and a bit of trigonometry, give or take a wavelength or few, you can calculate a good idea how much   the aerial needs to be angled upwards to pick up the signal coming over the hill.            Best regards, Patrick Holdaway (Shaw / Manchester)  Also see “Patrick`s Pictures” of a bodged Bacofoil aerial.

We are more than willing to give advice to those actually purchasing from us. Could those only seeking information please just find the answer somewhere on this site, or ring an aerial installer local to them, or call the reception advice phone numbers.

I wanted a long telly aerial cable with the right connecty things at each end so I could take a portable telly camping and actually watch it. It may surprise you that I'm no expert in such matters and I was just going to nick down to B&Q and hopefully happen upon the required gubbins off the shelf UNTIL I came across this website. It was so interesting, fun and informative that 40 minutes of work skiving later I picked up the phone and told the nice man at ATV what I needed. Less than 24 hours later, here it is sat on my desk. Brilliant!  Nice people, great service, quality all round. (M Leadbetter)

[Link] Thanks for the discretionary refund and for one of the most quirky and humorous websites I have found in a long time... Got the loft kit through, someone enjoyed packing that more than I did unwrapping it ! I must admit I am going to use the loft kit for an outside install but it's only for a DAB dipole; honestly! (well, to be fair, there isn`t much windloading on a DAB dipole). Just another word of thanks. My son has rarely managed to get many channels on the TV in his flat where it's connected to a loft aerial (he's not allowed an external one - I don't think he's even supposed to go in the loft...). Anyway, I removed the 1m fly lead from the wall plate to the TV (~99p with plastic plugs) unscrewed the wallplate and took out its innards. Pulled through some cable (there was just enough) and put a new co-ax plug on the lead. It looks a little less elegant (brown cable) but he can now get all the digital channels. Best regards Ian Royston

We`ve had a few E Mails from people saying the`ve had significant improvements by taking out crappy wall plates. Using a decent screened non isolated wall plate is an alternative to bypassing a budget surface plate.

Hi Justin, greetings from the sunny Borders. Thanks for the stamps - a kind gesture.

First: the FM half-wave dipole setup is giving excellent reception on both FM and DAB, where the built-in aerials on the radio sets were giving lousy performance. Money well spent, and all the info anyone could want on your excellent website.
[Link] This might amuse you: I've been helping my son move into a new (quite old actually) house. The TV wouldn't work. In the course of trying to figure out what was wrong I bought a new coax extension cable - the only thing I could get at short notice was a cheapo 4m cable from Argos.
To cut a long story short, the cable connection from the aerial was knackered, but we got full freeview reception from the 4m extension cable by itself,
not connected to anything! Add that to your list of improbable aerial setups. Thanks again for excellent service. Regards B Farish

It`s not unknown to get a signal with just the cable (i.e. no aerials at all), though it`s fairly rare and you do obviously need to live in a pretty strong signal area ! An interesting sidelight is that crappy cable is actually more likely to pick up a signal than decent cable because cheapo cable hasn`t got as much shielding. I can remember doing a set up at a house where the guy wanted his Freeview box tuning in but he only had an old A group aerial. Because at that time Sheffield/Crosspool had MUX1 on CH63 so I warned him he wouldn`t get the BBC channels because that MUX would be out of band. Imagine my surprise when I tuned his box in and all the BBC stuff was there, rock steady, no breakup ! He lived in a strong signal area and MUX 1 on Crosspool had just increased its output from 100W to 1kW. I`m fairly sure he was actually picking the signal up from his crappy old low loss CoAx and not through his aerial at all.

[Link]  Hi there. In my lounge I had a cheap plastic aerial splitter (1 male to 2 female) plugged into the TV coax socket on the wall to feed a Panasonic HDTV (with a built in Freeview tuner) and a TVonics PVR (non-HD). My local transmitter (Moel y Parc in north Wales) just moved some channels onto CH39. Prior to this, both the HDTV and the TVonics box worked fine and received all the channels I wanted. However, since the move to CH39, I could only receive the moved channels by not using the splitter. You suggested I should try swapping the splitter for the better quality metal co-ax splitter sell. You sent me one and it did indeed do the trick; I can now get all Freeview channels again on both my TV and PVR so thank you. I don’t know much about electrickery but it would appear that the old cheap & nasty splitter couldn’t cope with whatever frequency CH39 is on. Regards J Gray

An interesting report methinks. We can`t promise that upgrading from a cheap nasty plastic splitter will always have quite such a positive effect but this proves it does sometimes work, a better splitter`s only a few quid anyway so what have you got to lose ?  Actually, it`s worth upgrading anyway because the metal splitters are physically stronger and, even more importantly, they`re screened.

[Link] I just wanted to say thank you to Angela for her friendly & professional help last week. I was experiencing severe pixelation on certain channels and had phoned to place an order for a complete new system (aerial, brackets, cable, connectors, amp/splitter etc). After discussing the finer details of the problem, as well as environmental factors such as our location relative to the transmitter and aerial placement etc, Angela suggested I try just replacing my existing 6-way amp with a six-way splitter, rather than completely replacing everything as I'd planned. This was on the premise that Crystal Palace output power was significantly increased at switchover and the amp was probably just corrupting the signal.
I must say I'm extremely grateful for Angela's time & advice. I now have 100% quality on all channels on all 5 TVs in the house. Not only that, but it also saved me a considerable sum of money and, I suspect, a lot of frustration that would have ensued had I followed my initial plan.
I've already recommended you to a friend of mine who was also pleased with the service he received - prices & quality were also favourable compared to certain DIY stores ;-) .
Many thanks, indeed. Best regards
 (A Newland)

An E Mail which make a very important point, see signal strength and amp or splitter ?

When I asked for your advice a couple of weeks ago you could of told me and sold me anything. You did not. Before ripping all the coax out of all the rooms I thought I would first try quality cons and a four way splitter with F cons. I phoned my order on friday 4.30pm and was told I would receive it early the following week. Cool. Got up saturday morning and there it was. Postman must of wet bed as he usually comes around 1pm. Now lets not forget this is Jan and the country is covered in snow you must be related to that fat bearded bloke in the red outfit, anyway thanks for the advice, all TV's are working fine. We can all get back to ignoring each other. ATV you are tops and your site is informative and so funny.  C Ingham.

I stumbled upon this site whilst 'Googling' for information on how to choose and erect a TV aerial. I found all the information i needed right here and planned my install meticulously. Just to be sure I phoned up and asked for advice (just in case i had missed something) I was advised that even through a 6 way splitter I might not need the mast head amp, and I didn`t. The order I placed arrived quickly and my first install is now complete - I am so glad I did the job myself now as it has saved me a fortune. I have enjoyed trawling through this site immensely - I have particularly enjoyed the nuggets of humour (I`m particularly pleased to read this, it`ll annoy my wife…..) and philosophy scattered around the site and am still clicking on links here to ensure I haven't missed anything. Your site is unique and impressive and deserves credit from its users - when trying a new project of any type I always research thoroughly using the net, I love to save money and don't like being held to ransom by trades (neither do I).  

The idea of supplying a securing eye with the kit is brilliant - I am a pussy when it comes to working at heights (I don`t blame you, being careful when working at height is not Health & Safety Bollocks) and my double ladders were not really fit for the job but [when using the eye screw] were rock solid and gave me the confidence I needed - if you had of seen me working off the second from top rung of the ladder whilst clinging to the bracket and trying to secure the pole to it you would have not have been proud... but at least I wasn't wearing a hard hat and a fluorescent vest.

Thanks again guys, I will be ordering again soon as i need a TV aerial at my house in Boston too.

Thank you so much for such a useful mine of online information about all aspects of signal transmission and reception, the advice about the equipment required and the means of using it in order to obtain clear signals. The gain curves and dimensions of aerials is really useful. I especially like the links between various parts of the site to allow one to move across it easily when following a particular line of investigation. The online shop is simple and easy to explore. The website is superb, and perfect for us amateurs to learn from and use.
The advice and care of the staff on the telephone. Those to whom I have have spoken have been very patient, thank you, and so very helpful with technical advice and product descriptions. It has been a pleasure to purchase from you.
The very high quality of the parts that I purchased ( a mast head amp and PSU, wall plate, connectors and co-ax). The components have more than met my expectations; the TV reception challenges with which I was faced have been completely overcome, with some capacity in hand on the amp. When I compare the new equipment with the wall plate, co-ax and connectors that have been replaced (all of it installed new by a builder less than 18 months ago) the difference is stark; your products are vastly superior in quality to them all
So, I have a job well done at home - a very large part of which is thanks to your expertise and products.
Very many thanks and best wishes to you all.
C Malcolm
 (The chap in Salisbury, Wiltshire taking on a C/D group repeater from a small, single-storey loft, past some houses and through some trees)

* Builders may have the excuse of ignorance / lack of knowledge when they use cheapo stuff, but aerial installers don`t and most of them also use the same grade of products. The explanation being that aerial installers are notorious tight arses…….

[Link]  Thanks for the quick delivery of the 3 TV Fly leads. These are a massive improvement over the "other" cables I was using. Old ones were from amazon as an add-on, and are a complete waste of time and money. I’m a little bit wiser thanks to your website, and my tv reception is vastly improved due to your fly leads' thanks;)     P Murphy  (Oxford)

People really do underestimate the importance of fly leads, cheapo ones really are a poor investment. They may often work, but in significant numbers of installs they`re a contributory factor to the problem or even the whole of the problem. And, let`s face it, a decent fly lead is only £4, possibly only £2 or £3 more than a budget special……..

Back to the top

[Link]    I bought three fly leads (custom flyleads in this case) off ATV in an attempt to reduce or remove HDMI RF interference between my PVR and the TV. Before the changes I couldn`t get much reception on most channels at 1080p and lost Freeview HD and some SD channels on TV when the HDMI was carrying 1080i. If I unplugged the HDMI the channels disappeared.

Changing the crappy fly lead from the wallplate to the mast head amplifier PSU resulted in some HD returning at 1080i but not at 1080p.

Upgrading the cheapo lead between the mast head PSU and the PVR made no difference,

The lead between the PVR and the TV was replaced with one of yours and like magic, all the channels were then available, even when HDMI was connected at 1080p.

What I don`t understand is why cheapo HDMI leads seem to cause less interference than high psec one, are they operating at a different frequency???

(M Blow    Crewe)

I must confess I don`t know much about HDMI and all that, I`ve still got a CRT TV (as at 2016) and am quite happy with it ! But I feel certain this customer report will be of use to many people, so thanks ! If anyone knows the answer to the question at the end please get in touch and we`ll put it on here.

Hey Justin, I now have my Sky UHF signal distributed through the house again. Harmony is restored, more-or-less.
I've done a back-to-back
comparison of the Sky 'IO-LINK' and the one you sell using the Sony TV perched immediately above the Sky box and with 3' of co-ax between the link and the TV. Using the device you sell the picture quality might be a little grainier than I remember it and there's a very faint ghost image, but it's perfectly watchable, especially on a smaller TV. I cannot get a decent picture - I can barely get any picture - using the Sky device regardless of what I try. I've tested both of the Sky devices, so they're either both dead out of the box, or they are just crap.
I've had to try a few different UHF channels to find what I assume is a 'quiet' one without much interference. 68 was poor as were most of the higher numbers, 21 was poor too. I'm using 38 at the moment, just chosen by trial and error, and the picture quality is less grainy. I'm guessing that the signal strength is maybe a bit lower, because the old box didn't have any of these problems. Does the external 12V DC input have any influence of the signal strength, or is it just feed-through power for masthead amps and the like? If you've got any other ideas to try they'd would be very welcome.
Anyway, thumbs up for your device - not quite perfect but it works where Sky's "iO-LINK" simply doesn't. They're made in China by Global Invacom if you want to have a look.
I'm not even going to put the two I've got on eBay, I'd be embarrassed to take someone's money for them.
Thanks for the refund on the postage, much appreciated. I like dealing with honest companies. I'm sure I'll end up buying stuff from you again. regards, J Scott (Teeside)

Thanks for that, very interesting. I must admit I was a bit surprised that the Sky engr had said that Sky`s own I/O links had insufficient signal output ! To be fair to Global, some of their stuff is pretty good, I can only assume they built the I/O links to Sky`s specification.

After the March 2018 frequency changes, we retuned our receiver but found that BBC News HD had vanished. At Crystal Palace, this station had moved from Channel 33 to Channel 55 and our receiver saw a 0% signal on Channel 55. We thought this was because of our old Group A aerial but replacing it with a log-periodic aerial made no difference. What seemed really strange was that Channel 35 had moved to Channel 56 but our receiver could see that perfectly.

Justin at ATV suggested we try to eliminate any dubious aerial wiring in our house. We did this section by section and ended up checking the wiring of the aerial socket plate right behind the receiver. We found the installer had daisy-chained this socket onto a second on the same wall using this sort of arrangement. We were amazed to find that our receiver could see the missing Channel 55 (and BBC News HD) perfectly if connected to the second socket on the wall. As we never use the second socket, we disconnected it from behind the first and were delighted to find our receiver could now see the missing Channel 55 (and BBC News HD) perfectly on the first socket!

The moral is that you just cannot tell what subtle and unexpected problems you may have, or develop, if you engage in dubious wiring practises. Tricky chap Johnny RF!  (J Chittok   London)

A very interesting and useful report. Who knows the cause, possibly that the additional daisy chained outlet may have been generating reflections of the RF signal which happened to be out of phase at the point where the first TV was installed ? Whatever the cause, this is a good example of why daisy chaining RF outlets is a bad idea, though I`d be the first to admit most people would probably get away with it. (Link)

Oh dear, another aerial guy* who thinks he`s witty….

[my reply to an earlier E mail] Thanks for your interesting E Mail Jeff.

Of course, I think I`m right in saying, in Oz you have the opposite problem to British aerial installers. Over here if an installer falls off the ladder he gets a broken leg, but you float off into space don`t you ? Do you need a safety rope to prevent that ?

Not quite right Justin. In Oz we do fall but it is head first*. I only know one installer who has fallen off a ladder and he broke his arm.

*At least the fall is usually broken by an insignificant body part.

* Yet another if you add in Bill Wright and Sean Lambert…..

Hello Mark. A diplexer is the best way to combine two aerials (it minimises the losses and eliminates any phasing problems etc) but Belmont, being a wideband, means that one cannot use a diplexer and still get all the channels. It is possible you could get away with a 2 way splitter in reverse (as a simple combiner), you`d have to have a play to see how well it worked.

Hi Justin, thanks very much for your advice, it was much appreciated. I used the Yagi 18K aligned to Belmont and the SR10B aligned to Kings Lynn {Sandringham}. Fed both cables into loft and used a 5-2500 MHz splitter in reverse [as a combiner] as you suggested and then into my SLX 6 output amp/distributor. I then manually tuned channels 41, 44 and 47 from Kings Lynn followed by channels 30,53,60,33 and 35 from Belmont. All works spot on on my various TVs throughout the house. Tuning was a bit fiddly on some of the older sets,but got there in the end. So thanks again for the help and advice as well as fast delivery of ordered aerials etc. Mark Lawrence (Link)
