Diamond Antenna - MX-214 Duplexer

The MX214 DUPLEXER is used to transmit and or receive 2m and 220 MHz bands simultaneously.  With a dual band antenna, two bands can operate by feeding one coaxial cable from the antenna and connect the duplexer with two transceivers.  Or, with two duplexers, two transceivers and antennas can be connected with one coaxial cable.  Since each band output of the duplexer is isolated and unwanted interference is suppressed completely, isolation between output connectors is more than 45dB, simultaneous transmission and or reception can be achieved without interference at all.  And, by terminating the other output with a dummy load, this duplexer can be used as an effective lowpass or highpass filter to eliminate TVI.

Diamond Antenna's high quality duplexers and triplexers are used for splitting HF | VHF | and UHF signals. Duplexers and Triplexers are used to combine two or three transceivers to one coax feed line. Available models in both direct connections and extension cables for all mobile and base station installations.
