About Your FM Edge

Your FM Edge antenna is a quality indoor FM antenna which uses Gamma Loop™ technology to receive FM broadcasts with the least amount of noise possible.

Remember that no antenna can receive a radio signal that isn’t there. When a usable radio signal is present, your FM Edge will improve FM reception.

Note: Generally, a practical limit to radio reception is 40-50 miles from the broadcast transmitter depending on the terrain.

Gain Control Knob:

Located on the side of the FM Edge is the gain control knob. The gain control is the mechanism that either increases or decreases the antenna’s amplifier intensity. The further away you are from the radio signal, the more you increase the gain. If you are very close to the radio signal, lowering the gain may have a greater effect.
