RF Reception Maximization Strategies:
For proper and reliable operation, Listen receivers should receive a strong and consistent signal from
the originating transmitter. Follow these strategies should be used to maximize this signal:
a. When designing and installing a system, keep in mind that the location of
both the transmitter and receivers is critical to maximizing signal strength
b. Eliminate or minimize obstructions between the transmitter and receivers
c. Minimize the distance between the transmitter and receivers
d. Move transmitter and receivers away from metal objects
e. Place the transmitting antenna as high as possible (on stationary transmitters)
f. Orient both transmitting and receiving antennas vertically
g. On portable transmitters and receivers, the cable from the microphone or
headset is the antenna; ensure that the cable is not coiled or laying horizontal
CAUTION: When installing remote antennas, ensure the antenna is clear of power lines. Coaxial cable,
connectors, and optional antenna mounting kits are available from Listen. Visit
