Why in the world would I be getting *better* reception with a ANT751 rather than with a HD7698P? The RCA is three feet long while the Winegard is 14 feet long! Even when I bypass the coupler board on the Winegard (for testing purposes) I get results *no better than* what I can get with the RCA medium range antenna. What can I do to get better results out of my Winegard unit? Thanks fellows!
