My family has a cottage in Unoin Pier, Mi. We have two TV antennas. One points to South Bend and the other to Chicago. This summer we have been subject to sever UHF signal degradation. While I understand that sunspot activity can cause some signal scatter (like recieving WAOW-Wausau over WGN-TV), I can not understand the substantial increase of what I will call "white noise" on nearly all UHF frequencies.

I have checked all of my antenna orientations, connections and splits and nothing is "broken" or needs replacement.

What gives?

Do you have a PC near the feedline, and are the connections to the TV(s) and antenna good? How about digital cable running through a bad coax? A preamp in the line that's going bad?

PCs can generate garbage almost from DC to light (well, up to 3 GHz anyway. ;D ) and a leaky feedline can pick up all kinds of stuff. A bad preamp will do more harm than good. And, bad coax from the cable company will cause both their own customers and those nearby problems with radiation.

More than likely, if it's pretty much a UHF issue, it's probably your local or semi-local DTV's firing up to full-power. Most stations in your area (Chicagoland) are going to be operating on UHF once the transition to DT is completed. I, myself, am seeing an increase of "white noise" on UHF in my area (Boston) as well. Most of our major VHF's (with the except of our Channel 7, WHDH) will migrate permanently to UHF. WHDH will turn off their Channel 42 DTV and return to Channel 7 as a full-time DTV. I believe your Channel 7 (WLS-TV) will return to Channel 7 as well, as DT once the transition is complete. Hope this may be of help to you. I doubt there is anything wrong with your TV. However you might consider getting a set top converter so that you can continue watching most, if not all, of the stations you enjoyed on conventional (analog) VHF and UHF. You might even find a few stations you have never seen before. DT DOES do DX as well!

Good luck,
