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?

Many can be used either way. The ones that are made of low and high pass
filters are usually bidirectional and it does not mater which way they are
hooked up.
