I have more questions.....First do these in line signal amps work? The ones that sell for under $15.oo or so. Also after installing my SG2100 motor this week and finally getting it aligned I think, the signal strength on several sats is low. If I get a decent signal on say 95w,99w or 103w I lose white springs or maybe a few channels on 123W. Cant find that sweet spot to keep everything coming in. Do to the trees nearby I can't get anything below 95W anyway at this point. I've noticed several sats will be at the threshold point of losing the signal. Any ideas? Also what is the proper adjust on a KU lnb as far as the focal point? The distance to the dish...How do you know the correct distance 1/2" to 3/4" one way or the other? Closer or farther from the center of the dish. Thanks! Blind
