I have 2 OTA antennas in the attic for separate TVs (due to db loss in a splitter, length, etc.). One of the yagi antennas finds every channel (55) except channel 8 (KUHT) PBS in Houston. I am about 40 miles from all the local Houston transmitters. The other antenna gets all the channels and KUHT is just fine. Why would I be missing just this one channel on the second antenna? I have tried to find the frequency for KUHT but is only shows VHF-Hi, not an actual frequency. The antenna receives all UHF and VHF frequencies in this area except for channel 8.
