I never said I had good ideas. However, I realize that somehow you
better disconnect the connection when the VHF or radar is used. I
also forgot about impedance matching (my god, alzheimers, I taught an
engineering lab on impedance matching once). I really don't know how
a radar antenna works on small boats. If it is just a rotating dish,
it oughta work with the right transducer.

The kind with a dome has a printed-circuit board with an array of
little antenna elements with fixed phase relationship that produces
the beam and receives the echoes. The open ones are slotted wave
guides AFIK. I don't see how either would help a cell phone.
