I live in Ar. & we have the same problems when the temp drops bellow about 38 degrees we lose all but two of our stations, moisture is not the problem, as all coax has a copper center as well as I used a third wire coax with a built on ground wire, my question is the digital signal of the satellites to the antenea when the temp falls & moisture forms on antenea itself causing the problem, would also add we have multiple anteneas connected within and also prior to getting a hdtv we used a converter box & never had the problem we have now. I have done a signal strength & all the stations are pulling excellent reception, again it is only when the temp falls off do we have the problems, as soon as the sun comes up or about sunrise nbc then abc return as though the power output had been increased, cbs & pbs stay on thus far, the reason for more than one antenea was so we could recieve all networks that are available in our area which when the weather is above 38 degrees all is great, will add neither rain, or high winds bother the signal strength or the reception any other suggestions would be welcomed
I'm sorry, but your writing is virtually incoherent to me.
How can you possibly know the problem isn't moisture? You would have to personally blow dry every connection and the inside of every inch of coax. It wouldn't be related to the timing of rainstorms.
You say you did a "signal strength." Where? If you did it at the antenna when you were experiencing the problem, that proves the problem is with the connections between antenna and TV. If you don't believe it, hook a TV directly to the antenna with short, new RG-6 cable, and see if it doesn't come in just fine.
If you did the "signal strength" from the TV menu, and you did it when you were experiencing the problem, that shows there's a problem with the TV. (TV's menu says good signal, and you get nothin = probably time for a new TV.)
If you really think the converter was immune to the problem, connect it up to the HDTV just for a test. If that fixes it, again you have a bad TV. Hard to see how the TV could cause temp sensitivity, though. You don't have it sitting outside, do you?
Can't go any further into your question, cause I honestly can't read it. Maybe some periods would help at the ends of sentences ... ?
