Just installed antenna (RCA ANT751) in attic, including a pre- amplifier (RCA TVPRAMP1R). Reception is GREAT on upstairs TV closest to antenna and am receiving all channels I should be. On the TV downstairs though, I am not receiving NBC, ABC, and FOX.
The length of run downstairs is probably on the order of 75 feet of cable (RG-6 quadshield). Is it likely my pre-amp is too small?
I used antennaweb.org to find optimal pointing direction and I am pointed there. I tried about +/- 30 degrees of the recommended bearing with no change. The antenna install instructions say to point the small end of the antenna toward the stations you want to receive. They don't mean the nub sticking out from the mast attachment point as the small end of the antenna do they? If so, I'm 180 out, but probably thinking that's not the problem.
The TV downstairs is new, but not so zesty (Colby 19"). Is it possibly a TV problem- weak tuner? I'm thinking probably that's not the problem either though.
Anything else it could be? Any suggestions? If I need a stronger pre-amp, any recommendations?
Thanks and any help greatly appreciated,
