Helpful Information
About Your AM/FM Tower
Remember that no antenna can receive a radio signal that
isn’t there. When a usable radio signal is present, your
AM/FM Tower will improve AM and 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 front of the AM/FM Tower is the gain
control knob. The gain control is the mechanism which
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, signal saturation occurs, lowering the
gain will decrease the amount of distortion.
