As expected the A group aerials display the biggest superiority in gain over widebands. In fact such is the widebands inferiority that there is no such thing as a “High Gain” wideband aerial for the A group frequencies.


The dimensions of the aerials can be found on the relevant table.


The prices of the aerials are on the Aerials Shop page.


Also see gain curves of other A group aerials.

K group aerials have significantly more gain than widebands at the bottom of the band. In fact there is no such thing as a “High Gain” wideband aerial for the bottom of the K group frequencies.

An E group aerial is a “semi wideband” whose response is optimised for the middle/top of the band, at a cost of some gain down at the bottom,see Group Gain Curves.

I`m not really a fan of wideband Yagis, but as one can see from the graph the DY14WB has exceptional performance. Bearing in mind the fact the DY14 is only 5ft long its gain figures are remarkable and this makes it reasonably suitable for loft installs

Notes.

There is no wideband aerial which will give “high gain” at the bottom of the band. If you must have a wideband, and you`re sure you require more gain at the bottom end, you`re best option is to diplex an A group with an E group, or even an A group with another (high gain) wideband if you already have one of those. Remember that most people don`t need a “high gain” aerial though !

The above table is a summary of the A group results, see full results.


In our tests other models of 18 element A group gave around 2.5dB (average) over the A group (relative to the DM log).

B Group Aerials

The above table is a summary of the B group results, see full results.

In our tests other models of 18 element B group Yagis gave between 4.2dB and 4.6dB (average) over the B group, relative to a DM Log.

C/D Group Aerials    


The C/D group will be obsolete from 2020, thus, we ceased stocking them from January 2015. We advise the fitting of an E group instead, something we`ve actually been recommending since 2011 anyway ! E groups are wideband aerials with a bias to the top end of the band at the expense of a bit of gain at the bottom.

Also see C/D group gain curves

K Group Aerials   The K group will be the “new wideband” from about 2020

(more or less)

E Group Aerials

The above table is a summary of the E group results, for full results click here

The above table is a summary of the wideband group results, full results


Typical models of Yagi 10 element wideband average between 0.5 and 0.7dB *.

Typical models of XB5 wideband average between 0.9 and 1.3dB *.

Typical models of Yagi 18 element wideband average between 1.5 and 2.3dB *.

Typical models of XB10 wideband average between 2.0 and 3.8dB *.


 * All figures are average over the whole T group relative to a DM Log.

ATV Stock Aerial Tests      


This page contains the test results for all the aerials we recommend/stock for the different groups. The results, from our aerial tests, are arranged in tables as follows :


The A group aerials we stock

The B group aerials we stock

C/D group aerials

The K group aerials we stock

The E group aerials we stock

The Wideband / T group aerials we stock


Also see ATV`s tests of FM / DAB antennas


Note that TV frequency band after the 700MHz clearance (to 2020) the K group will be the new wideband. Well more or less, because the esoteric HD MUXES (7 and 8) will be transmitted on CHs 55 and 56, so for those who want those channels a wideband (or Yagi18K which works higher up the band than other K groups) would be required. MUXES 7 & 8 are due to be switched off sometime between 2020 and 2022 though.

The above table is a summary of the K group results, for full results click here.
