I have for sale a Diamond MX-72 2m/70cm diplexer, great for using for using 2 different antennas with a radio that has a single antenna connector-like most VHF/UHF radios do today. Or use it with a single dualband antenna with 2 antenna connectors, like on the Icom 9700 and other satellite radios.
The input connector is a SO239 jack and it has leads for the outputs, with PL259 connectors. I can provide a SO239 to N male adapter if you need that for the UHF side.
I am asking $32 shipped in the US, and I can take paypal/check/MO.
