I've been using a basic antenna for quite a while now, as I only really want the late night news broadcast. Been working okay.

But Wednesday (two days ago) a new tenant moved into the apartment next to mine. I've learned that she doesn't yet have a tv, so I suspect some other electronic device might be the "culprit."

I get a great clear signal and picture from different broadcast towers all day and into the evening, when I turn the tv on about 7:30 pm. Then I use a non-broadcast input.

When I turn back to see the news about 11:00 pm, there's no signal whatsoever. But later, sometime shortly after midnight (i.e. going to bed time?) I can get a clear signal and picture again.

I suspect, and only suspect as I haven't had a chance to speak to the new tenant yet, that she's using some kind of electronic device during the evening that blocks the broadcast signal from my antenna.

This is really weird, and I will get a chance to speak to her, but she could be as clueless about the whole situation as I am.

Any ideas as to what might be blocking the signal completely (totally dropped, not just weak, and from more than one broadcast tower) for the few evening hours?
