Re: QCX mini: RF output BNC or SMA #poll-notice


How about MCX? Rated for 500 cycles... I have a DSO Quad pocket oscilloscope that uses them and they're pretty nice for quick setups.

Absolutely not SMA!

Used to have a Heathkit 20m rig with an RCA connector. Ran 100W through it. Never had any problems.

An RCA phono would be a good choice also.

I am also a supporter of a BNC with SMA alternative PCB pad but I accept that might be awkward with a case end plate.

Collins Radio thought RCA connectors with the little ceramic insulator inside were great and were 50 ohms......for desktop use only, however. No mechanical stress on the external cables.
