There have been numerous postings about antennas, but none recently that answer my question. I use a Direct TV HR10-250 HD TIVO for satellite and OTA signals. I could write many pages praising the performance and user friendliness of the HD TIVO. Recorded HD picture quality on my Toshiba 57" RPTV is not visually different from the original live picture. My location is 50 miles south of Green Bay, Wisconsin. I use a Radio Shack VHF/UHF antenna in my attic. It receives seven of the eight digital stations OTA very well. The NBC channel 26-1 (41 digital) is marginal most of the time. Signal strength is usually about 50%. The others all run from 65% to 90%+, using the TIVO program for checking. I have tweaked the antenna aiming, amplifier, and wiring (RG6) and cannot get a reliable digital signal for this one channel. Are there UHF only antennas that may work better for digital channels? After all, they are all in the UHF frequency range. Comments and brand suggestions would be appreciated. Thank you.
