There are antenna companies that are rating their antennas in mileage with claims of 100 to 150 miles. The height of the antenna at your home will also affect the range and performance of the receive signal. Terrain & foliage between your home and the tower will also affect the quality and ultimate range of the signal. Transmitters also have various licensed transmit power, which is licensed and regulated by the FCC. Many towers are placed on the highest ridges to add distance to their signal profile. The elevation of these towers relative to the surrounding service area is a factor. They can vary in height from a few hundred feet high to 1000’ or more.
