Diplexer.
(See Figure 1-3.) The BDR diplexer provides a method of using a receiver and a transmitter on a common antenna. The
diplexer has three coaxial connector ports - one port connects to the antenna via the power supply and the other two
connect to the Radio A and Radio B ports on the BDR. The diplexer, when properly tuned, provides a transmitter-to-
receiver isolation of 70 decibels (dB) at any frequency spacing of 4 MHz or 3% of the operating frequency, whichever
is greater. There are three separate diplexers, one for each frequency band. The frequency band of the diplexer must
correspond to that of the receiver-transmitter and antenna.
