This low noise broad band Pre-amp AT-PAA28 is designed to boost weak TV signals to compensate the signal loss of long running cable and noise of the receivers.
TV signals are very complicated and different from location to location. Do some research on TVFOOL, and get basic channel/signal information of your location before buying an pre-amp.
Scenarios and results you may get:
1. Weak signal only (You may see great results using this Pre-Amp, EASY)
If your location are far from TV stations or you can get very weak signal even by a high gain antenna. Basic setup as per instructions are sufficient.
2. Some directions have strong signals and some directions have weak signals.(You may see good results when tuning the antenna system well, EASY-ADVANCED)
Try to point the antenna (Single antenna system) to the weakest stations, in this way more weak signals and less strong signals are received in the system. If multi-antenna system is used, use higher gain antenna to get weak channels and connect to the amplifier, and low gain antenna to get strong channels without amplification. Signal combiner may be required to get best results;
3. Weak signals among lots of strong signals and are coming from the same direction(Complicated and special setup may be required to get weak channels extracted, ADVANCED).
Weak signals may have to be separated from main stream before feeding into this pre-amp, then can be combined back to the main stream. Lots of tuning and testing may be required due to complicated signal strength and frequency distributions.
In scenario 2 & 3, advanced setup skills, as well as additional components may be required to get better results.
