Hi: I have basic TV split 4 ways in my home and figured a signal booster might help improve the picture quality (currently I get a couple bad channels; this is magnified w/ the TIVO too). I've seen the radio shack ones but wanted personal opinions on how they've worked. I was going to pick up the 1:4, but installing it would be a pain in the butt. My questions: -given the 4 way split, would it be okay to just amp the signal right before the split? -How much signal boost do I need? -if so, what amplifiers/boosters have you used and been successful with? Here's one I saw at circuit city the other day... http://www.circuitcity.com/frame1.js...=0023143004302 I know the answer I will get is 'go out and get direcTV', but not exactly an option at this point due to struggling economy, impending war, blah blah blah =D. Thanks in advance.
