Duplexer technical specifications
An optional duplexer can be used with the repeater. The
duplexer allows the repeater’s receiver and transmitter to
operate on a single antenna at the same time. When operating
within neighbourhoods where other RF devices are installed,
including broadcast antennas and microwave link transmitters,
the duplexer prevents interference with other RF devices.
The duplexer must comply with these recommended technical
specifications.
