I'm helping my brother install a hd7694p. He lives about 30 miles east of Pensicola, FL. He was able to get about 15 channels or so with his omnidirectional antenna that lies flat inside his house. However, with his new antenna we get no signal whatsoever. The box did not come with instructions, so I downloaded the pdf off of google. This is the 5th Winegard antenna I've put together for people, so I'm not a rookie. We did a channel scan and pointed the antenna in different directions.
Nothing whatsoever. We tried two different coax cables. Is there anything else I can possibly try to troubleshoot?
