After countless hours trying different antennas, antenna heights, pre-amps, etc, I pretty much gave up and started playing around with digital reception. The digital reception looks very promising - I get a good, consistent signal for 5(uhf 29), 7(24), 9(30), and 11(12). But, surprise, surprise, I can't get a good signal for FOX2(56) and KRON4(57).
Now, all of these stations are broadcast from the same tower, so what's the deal with 56 & 57? The only obvious difference is that they are at higher frequencies than any of the others. Is this some type of interference? If so, are there any devices (filters, etc) that I could consider?
A couple of things to note:
1. There are some larger power lines (the kind that run from city-to-city) that cross right in front of the direction that I am pointing. They are about 200-300 yards away.
2. There is a guy about one street north, and about 100-200 yards east (away from the power lines) who is using the same setup as me (CM 4228 + CM pre-amp), and he is getting 56 & 57 just fine. In fact they are his strongest signals.
3. I took my receiver (Hughes HTL-HD) over to his house and hooked it up to his antenna just to see if it was something wrong with my box, but low and behold, I was getting about 90% on both 56 & 57 (I get about 20% at my house - not enough to even hold a signal).
Any thoughts? Please, any ideas or advice would be much appreciated. Thanks.
