Tv Antennas and Reception
Three situations come to mind. #1 Tv antennas are very wide frequency band antennas and as such are a compromise design , Tv antennas have a lobe pattern and the lobe pattern is a little different at different frequencies/channels. #2 The transmitter may not be in the place that is indicated or might have been moved to a different location. #3 Multipath (reflected signals) might be the situation.
