We have found that many viewers that have TV reception issues are using indoor antennas. In many of these cases the viewers are having intermittent reception problems. One day the service works ok and the next day it is not available. In some cases all the channels are received but the signal will periodically drop out or pixelate.
For viewers that are in encountering issues with indoor antennas we recommend trying a VHF/UHF outdoor TV antenna. Installing an antenna on the outside of your home provides potentially better reception because the signal does not have to penetrate building walls or windows and is normally at a higher elevation.
