Anyone have experience using a single Comant CI-121 to feed to COM
radios with the Comant CI-601 diplexor?

And, anyone have experience feeding a GPS and COM with the Comant
CI-2480 antenna?

I have 3 antennas on the roof of the fuselage (COM1, COM2, GPS). It's
going into the paint shop soon, so now's a good time to consider
minimizing the clutter up there.
