I have a Clearstream C4 antenna mounted in my attic directly to a truss and pointed southwest. I live at zip code 32446 and the main channels I want to receive are (NBC,CBS,ABC,FOX). They basically all broadcast from the same general direction at about 30-35 miles away. The RG6 cable running to my tv from the antenna is about 80 feet long. My house is a single story with a normal shingle roof and the antenna is mounted approx. 15 feet high. RIght now all I can receive digitally is 4.1(CBS), 13.1(ABC)....I can't get a signal for 7.1(NBC) or 28.1(FOX). Does anyone have any type of advice? I REALLY don't want the antenna mounted on my roof. I want to keep it in the attic and eventually run it to three other rooms. SOMEONE PLEASE HELP!!!!!!!
