Key Concepts in Value Package Setup
Antenna placement (rear)
Rear mounted antenna
Rear mounting the LA-123 90° Helical Antenna (72 MHz) will allow the transmitter to be moved if necessary.
For proper and dependable operation, Listen receivers need to receive a strong and consistent signal from the
originating transmitter. The following strategies should be used to maximize this signal:
Maximizing Transmission Range
Transmitting antenna
When designing and installing your system, keep in mind that the location of both the transmitting and
receiving antennas is critical to maximize broadcast range. Minimize the distance and remove any obstructions
between the transmitting and receiving antennas. Keep transmitting and receiving antennas (receiver earphone
cord) away from metal or conductive objects.
RF Power switch
Position the RF Power switch on the back of the LT-803-072 to full RF Power, unless lower power is necessary.
Low, med or high RF power
