The antennas we offer, both amplified and non-amplified, are made for specific distances. The non-amplified antenna works wonderfully for customers that are in a 30 mile range of their transmitting towers while people more than 30 miles from towers tend to find success with our amplified antenna.
An issue that can sometimes occur when you are using an amplified antenna is poor reception when you are very close to the transmitting towers. The signal from the tower can overpower the amplifiers on over-the-air antennas and they won't work with the amplifier on them. To resolve, we would recommend removing the amplifier and re-scanning for channels. Other customers with a similar situation to yours have had success with this.
