Limited tower or rooftop space at radio sites means some RF designs incorporate a single antenna for both transmit and receive operations. 

RFI's Duplexers enable the use of a single Tx/Rx antenna by providing the required isolation between the transmitter and receiver paths.

A wide range of Duplexer options are available, ranging from compact notch duplexers for mobile applications, larger cavity duplexers in various configurations and sizes, to compact milled aluminium duplexers supporting medium and high-power requirements. 

RFI have duplexer products available covering traditional bands up into the cellular bands with appropriate mounting hardware.
