I think we need more info. The CG has NO control over OTA signals. Per Law, ALL OTA signals are HD Digital, with only a few Analog exceptions. The CG MUST have been supplying their own CABLE type reception with the RV'er connecting to the CG internal wired Cable network. In other words the poster was NOT receiving OTA (over the air) antenna reception at those CG's. So, what he must be experiencing is Digital boost of OTA signals which his old TV's cannot receive. So, he can either buy new HD TV's or just buy the Analog to Digital adapters they had over 10 years ago. Cheaper than buying new TV's. Of course, this makes for a good excuse to upgrade the RV TV's:B Doug
