I live in Waynesville, NC and am having a problem picking up CBS channel 7. I have a Winegard HD8200U antenna and a Winegard 8700 preamp. There is 4ft of cable going from antenna to preamp, then 50ft to ground block. From the ground block there is 50ft of cable going to the Tivo box. This is my TV Fool profile

4-82%
7-27%
13-70%
16-50%
21-74%
33-90%
38-46%
40-75%
62-21%
Any help would be highly appreciated.
