Single Channel System

A single channel system consists of one LT-82 transmitter and one or more radiators. The diagram below shows such a system with one radiator. The radiator is powered from the power supply at the transmitter. This power supply can supply enough power for the LT-82 and up to two LA-140 radiators. If you need more than two radiators, you will need more power supplies. This is discussed later in this document. Power is supplied from standard CAT-5 cable while RF from the transmitter is delivered using 50-ohm RG-58 coaxial cable. The radiator is supplied with 25 feet (7.6 meters) of CAT-5 and RG-58 coaxial cable.
