I am confused on some issue of a diplexer. Sometimes,people say that
it is a device which used to split the signal from one source to two
loads i.e., it is used to split the signal from a dual band transmitter
fed on the same coax to two different antennas. Somtimes, they say
that it is the device that used to combine the 2 signals from two
different antennas to one receiver. Which one is correct?
Are they the same device?
