RF Reception Maximization Strategies
For proper and dependable operation, Listen receivers need to receive a strong and consistent signal from the originating transmitter. Note that on portable receivers the headset wire is the receiving antenna. The following strategies should be used maximize this signal:
1When designing and installing your system, keep in mind that the location of both the transmitting and receiving antennas is critical to maximize broadcast range.
2Eliminate or minimize obstructions between the transmitting and receiving antenna.
3Minimize the distance between the transmitting and receiving antennas.
4Move transmitting and receiving antennas away from metal or conductive objects.
5Place the transmitting antenna as high as possible.
6Orient both transmitting and receiving antennas vertically.
7Position the RF Power switch on the back of the
8Keep coaxial cable from transmitter to antenna as short as possible.
CAUTION: When installing antennas, ensure the antenna is clear of power lines.
Coaxial cable, connectors, and optional antenna mounting kits are available from Listen. See page

If you need to run cable over a length greater than 50 feet for 216 MHz applications or greater than 100 feet for 72 MHz applications or to maximize broadcast range, Listen recommends that you use
Long cable runs can result in signal degradation due to the “loss” characteristics of the cable. When using
