We have an old RV-3090 Sensar antenna. When we try to receive digital signals, all we can get is channel 11.1 which is broadcast on RF channel 10. None of the UHF channels are able to be received. When we use a indoor rabbit ear DTV antenna, we can get about 5 more of the channels on UHF but not the VHF one we did with the Sensar...it appears that the Sensar is only receiving VHF signals and not passing UHF to the TV.
Is this a possibility? Do we need a new head (RV-2005) to the antenna system?
(We are in zip code 30286)
