I am currently using a VHF/UHF indoor powered antenna. A couple of my locals are VHF, the rest UHF. I am having trouble maintaining a reliable reception for two UHF channels. I was thinking about getting the Silver Sensor, but I need my VHF locals. Is there a way to use both antennas with the STB? I'd appreciate any help. Outdoor antennas are not feasible because of space limitations, and I have been tweaking the loop for 8 days now.
