using Antennapoint, it shows you at least 35 miles from your TV towers. Depending on the terrain, that is about max for any RV antenna, even with the amplifier. We have received a signal at 65 miles over very flat terrain, but it also would go in and out depending on the weather and atmosphere conditions. Your antenna and setup are probably OK, just your range. If you are using the Winegard Sensar, it does indicate that too MUCH gain can cause the problem, so you might check that. If the meter says that you are losing the signal, it is probably atmosphere. Sorry, thats how digital works.
