I'm running two tvs off a roof antenna with a rotor. A cable splitter is used with one cable running to each tv and its converter box. Tv1 has a relatively short cable run, Tv2 has a very long run around my house. The splitter is close to Tv1. For a certain weak channel, picture on Tv1 was good although signal was marginal (digital pictures being either good or broken up); picture on Tv2 would breakup occasionally or be unwatchable (no picture at all).
I installed the amp just downstream of the splitter-out connector to Tv2. Before installing the amp, I could not receive the weak channel in question on Tv2. Afterwards, and based upon one days viewing, I experienced no picture breakup on Tv2 with a marginal signal strength similar to that displayed on Tv1.
As I write this, Tv2 signal strength for the weak channel in question is ranging from 45 to 60% with no picture or sound breakup. Signal strength for a good quality picture should be 65% (in the green) according to my Digital Stream converter box.
The antenna rotor is directed to what seems to be an optimum direction and not changed for each channel.
Further improvement would be to add another amp just upstream of the splitter or make my cable runs shorter, as I have much excess.
