REPEATERS

A repeater system consists of a linked transmitter/receiver
combination installed in a prominent location . The repeater
is designed to receive signals on a designated channel and
re-transmit them on another channel .
Repeaters are usually located on hills, mountains or tall
buildings . The increased elevation greatly improves the
range of the repeater beyond that of a normal base or
mobile . This means that the repeaters are able to receive
and retransmit signals to radios that would otherwise be
out of range of each other .
