Because it was unlikely that I would be getting a couple of my HD channels via Dish anytime soon, I had a crossfire antenna 3677 and channel master 7777 oreamo professionally installed. I live in a valley about 40 miles from the transmitters with lots of mountains between me and the towers. To my surprise I get signal strengths in the high 60's and 70's on my 722 and also on my 622 Dish receivers. But I am having two problems.
First, all the transmitters except wypx are on the same antenna farm in the Heiderbergs. However, I am not able to receive WRGB (39) WCWN (43) and WYNA (15), but WTEN (26), WXXA (7), wmht (34) WYPX (55), wnyt (12) all have the same signal strength of 68-72 on my dish receivers. Numbers in parentheses are all real and not virtual channel numbers.
Second, wten will be on for 15 minutes and the signal will then drop to 0, then it will be on for several hours and then drop out, channel 34 also gets dropouts but less so, 55 even less so, 12 even less so, and 7 will have blocking but never goes to 0. The problem seems to be greatest during the day.
The installer tried over pointing the antenna (which should have ok directionality to begin with) to try see if that would help. The stations are at about 10 o'clock and he pointed them up to 11 and down to 9. We disconnected the pre-amp to see if that will help.
WRGB and WXXA are the two most important because they are unlikely to be on Dish in HD. After Feb, WRGB-HD will be on real channel 6-1. Since the VHF seem less affected, things may be fine then.
He suggested that the problem might either be multipath because of the valley, or WCDC (34 digital, analog 19) which is about 13 miles a way and transmits to most of western mass and southern vt and even NH, might be overpowering the antenna. Channel 19 is about 2 o'clock. If it is overpowering the antenna then again I should be fine come Feb. I can not receive 34 - it has 0 signal.
Also in the equation are a radio FM antenna at about 5 o'clock so behind the antenna and a metal cage over the chimney (in front of the antenna) to keep animals out. There are trees, but no building taller than 2 stories.
I am also getting a converter box to see if that tuner exhibits the same issues.
Because I can no longer walk steady enough on a roof, I will need to get someone back.
So my question, is what are the best guesses before getting someone else to look at the situation?
Thanks.
