My radar plot:
http://www.tvfool.com/?option=com_wr...1dda681c90a0f3 It assumes 10 feet height, which is wrong but i didn't know how to find my exact location AND have the antenna height option.
I zeroed in on aerial photo to exactly where I want to put tripod and antenna. I have no existing antenna, amp, etc. The only channels I care about
: reliable reception for ABC, PBS, NBC, Fox, CBS; any others are gravy. I want to serve 4 tv's: one in basement, one on first floor, 2 on second floor. I believe I can use my existing cable tv coax infrastructure, at least in part. Peak of my upper roof is about 30 feet. I'd use a 5 ft. tripod (maybe Ronard 911?), mounting it on my back porch roof. My house ground rod is directly below (actually 2-3 foot north) of that point. I can enter with coax from there too via an existing hole in siding (PVC pipe left from old propane furnace) - That pvc pipe hole enters to basement (close to a 110 outlet, in case I need distribution amp), then I hope to tap into existing coax infrastructure from previous cable tv to distribute to 2 of the Tv's. It's close to 13 feet from porch roof mount location to peak of upper roof; figure I need tripod and mast to total 15 feet - which would put it 30-32 feet above ground, just peeking above upper roof peak. Looks like channels I want are all green-yellow. Would I need to go to peak of roof, say 32 feet, to get them? No trees close by within 100 yards to south, SW, SE... maybe in 30 years, but not now. What antenna and mount? Will I need distribution amp?
