wish to combine VHF rf tx signals into one antenna

[Zachary Yarashus]

Actually, the duplexer might work better than that... I saw a mobile setup
demonstrated in which there was a single antenna, and two transceivers. One
radio could transmit without observably diminishing the receive performance
of the other radio, and vice versa. They could also transmit or
receive simultaneously. Though in general they might not need to do that, I
thought it was rather impressive.

By the way, is it duplexer or diplexer? I've generally heard duplexer, but
are these just two different names for the same thing?
