How is a repeater configured?.
A repeater normally consists of a receiver, a transmitter, an antenna, and a repeater controller (which controls the retransmission and various other functions). Many repeaters also use a duplexer which allows the use of a single antenna for simultaneous transmitting and receiving. The most popular band for repeaters is the 2-meter band (144 MHz), with the 440, 222 and 50 MHz bands following closely behind.
