I've been on the roof for several days now (not consecutively, of course...though sometimes it feels that way) and I need help to resolve a problem w/my OTA digital station reception. Here's my situation:
Dish 6000 w/8VSB.
(2) Radio Shack UHF only attennas mounted on a 5' mast on the roof (2 story Cape).
The antenna leads are joined by a Channelmaster unit that joins the 2 signals (antennas are ponted in the opposite direction from each other) and sends a single signal to the receiver.
100' run of RG-6 cable from the antennas to the receiver.
I am located less than 30 miles from all of the digital station towers (relatively flat terrain as well).
I am able to receive signal strength of 60 or > on all of my local digital stations.
My problem is that I see very significant dropoffs in signal strength across all of my local channels, regardless of how close or far I am from the tower (that is, the dropoff for the closest one is no less than the farthest one). Signal strength of 80+ one minute that drop to zero...back to 75...back to zero, etc. Obviously the dropouts include picture loss, etc.
I have re-pointed the antennas several different times and the problem persists. I've had a taste of these high quality pictures on my Mits 55" ...but it's been a tease to this point.
Any help or recommendations ? Is it a bad cable...bad 8VSB...bad receive...do I need an amplifier...Help!!!
Thanks in advance...
