npub178rvtslm3qykq8uy5afswta2qz5pk9atjxsepht4x8ldddssp6kq4sqekt (npub178r…qekt) Some of those send/receive frequencies are close together. It's an impressive duplexer or filtering that can keep them apart. I suppose a big oceanliner might put the two antennas on different ends of the ship, to shave off some of the first big heat-things-up transmit dBs from the received signal.
Wow. A lot of work, all part of helping civilians to this day not understand puch-to-talk.
