All cabling is RG6.

The tuning varies from TV to TV. For example, I can watch 7.1 on the Polaroid and the RCA TV, but the Sony shows no picture on 7.1. While that is happening, the Sony will show 9.3 (with a 89/100 strong signal), but the RCA (Tivax) and the Polaroid will show no picture on 9.3.

The Sony is physically closest to the Winegard amp inside the home, and the antenna for that matter. If being closest was a true benefit, however, I would expect the Sony to display everything (keep in mind it shows nothing on 7.1). There are other channels that are doing this too.

Before I start swapping stuff around and crawling under the house (I hate crawlspaces), is this normal? Has anyone else seen this type of trouble? I live in a valley that is probably considered fringe for reception (hence the high antenna mast).

Any ideas would be appreciated. The Polaroid is easy to move around for testing... the Sony is a 250lb CRT and the RCA is a big CRT too.

Thanks! - Walter
