Just to add my experience, I'm 7 miles from the tower. Indoors I would
get 25-84 signal with 50' of rg6 cable. I moved my antenna outside and
to 100' feet of cable to a wall plate, 50' of cable to a 1-4 splitter,
1' of cable (To each of my 2 pcHDTV cards) and I get 88-95% signal
constant on every channel. I had bought a 25db gain amplifier but
didn't need it after moving the antenna outside.
Even indoors with that amplifier I still rarely could get a good/any
signal on 3/11 stations. Just moving outside, and though adding all those
extra splitters, wall plates and cable gave me a much better signal. I
highly advice anyone doing HDDTV to keep the antenna outside. In my
attic, with amplifier I never got a good signal (Had to go through 3
walls before it went outside from where I could get in my attic).
