Description
Fully screened Mast Head Amp with inter-stage variable gain suitable for between 1 and 4 points. The amp will not pass FM/DAB, if required this should be diplexed in after the amplifier. The amp can supply one to four TV points, or more via a splitter with power pass. As an example, if the amp were turned up to 16dB and then sent through a 4 way splitter (with a through loss of 8dB) you would still have a “nett gain” of 8dB per output, less any cable loss. The weatherproof enclosure makes it equally suitable for mounting on the aerial mast, or on the wall, or in the loft. The plastic housing is removable, if required, so the amp unit can be screwed directly to any surface, e.g a loft joist. The amp is not cascadable, which is usually a good thing……
Max recommended distance from the PSU to amp would be well over 250m, though that is purely theoretical because the signal (travelling in the opposite direction) would never get as far as that, not in a usable form anyway.
