I typically double-up the wire and use the red (18-22 g) connectors.
That's what I just did. I needed to get the job done without delay. I had an assortment of good heat-shrink connectors and just got it done, long story short. I wrapped the connections in electrical tape, then heat shrink tubing over it all. Considering it should never be under any strain or exposed to water, I'm quite satisfied. The job is done. It looks clean and it's as strong as 22AWG can be.
Such a tiny little thread of a wire, with such an important job.
Share my joy! I now have a 100% brand new VHF system, from microphone to masthead and all points between. Bigger, better, 35 years newer. Best of all, we're in the DSC club now. Very excited about that.
