A mast head amplifier is designed to amplify lowsignal levels for both analogue and digital applications. The amplifier gain should be selected to suit each individual environment.
A UHF gain control allows up to 10dB variance of UHF amplification. Price includes power supply transformer.

I have been involved in resolving TV reception issues here for many years, and have tried many brands of masthead amps. I find Kingray are the best and I support Auzzie made where possable. As Satplus replied to you, you do need to check your signal levels. Fortunatly for me, all my UHF signals here are of a similar level but usually a high level compared with our one VHF transmitter signal. In these cases, high gain is required for VHF and sometimes I find it is necessary to reduce the levels of my UHF signals to avoid reception problems.
I have NEVER had a problem with the Kingray units, just the large difference of levels sometimes which requires me to think outside the square sometimes.

Connect the Masthead amp, tested voltage was present all ok, however I received half as many stations as without the Amp. Tried combined, UHF, VHF all combinations. The statations the Amp provided were clearer, however only half as many.
Terrestrial TV signals can be difficult to amplify and they often arrive at the masthead at very different levels. This sound like some of yours are higher than the rest and are possibly getting saturated by the amplification. It may be a good idea to get in an antenna installer who uses a good signal level meter. I am sure you will then find that the amplifier works well. Philip.
