My apologies for the long-winded post, but I wanted to provide enough info.
Here's the report:

I'm really just interested in getting the 3 main network channels to the N, and the 2 to the S.
Here are the details. We had a large roof-mounted rotatory antenna that was 20 years old. Reception was pretty good, but stations to the south (PBS) did not come in all the time. Since the old antenna was missing several elements and the coax was also 20 y.o. I decided that a new antenna and RG6 cable could only improve reception. I was wrong. This is the antenna I bought:

It is slightly smaller than the old one. Has a 100' RG6 coax, only 1 TV (although I'd like to have 2 TVs). Reception was very spotty at first, and only the 3 stations to the N (ABC, NBC, CBS) came in. I then added a pre-amp, which improved the reception of those 3 stations, until recently when they started dropping off the digital cliff every so often and I'd get a 'no signal' response, sometimes lasting for days. This seems to happen when it gets hot and humid or rains.
My guess is that I need a larger antenna, but before I sink another $150 into it I wanted to get some advice from the experts. Any chance that the pre-amp is interfering with the signals? I've tried it with and without the pre-amp when I don't get a signal and it hasn't made a difference.
What are the chances that raising the antenna another 2 feet would make a difference? It is now about even with the peak of the roof (which may be why we have trouble getting signals from the south since the roofline is in the way??).
Thanks!
