Well, as I said, I am not sure what equipment I have, my antenna guy (whom I trust) installed it for me a few months ago. I know that it is on the roof and it has a rotor. I live about 3 mls. W of downtown. If I point my antenna East, I can usually get reasonable reception from Kansas City for UPN, CBS, ABC, and NBC, as well as Pax from Lawrence. However, in recent weeks I have had troubles with some of those stations, primarily UPN, and it seems to be related to weather conditions.
So my question was more in general about how the weather affects reception of digital signals. It was moved by the moderator to the Topeka area thread, but I am not sure it belongs here, it is a more general question on how digital signals travel and are affected by external conditions.
Thank you for your reply.
