2 VHFs? I have 2, but my handheld won't do DSC...... (and there is of course now the DSC handheld option which negates the battery problem as well!)

Plenty of connectors out there with latching mechanisms.

I intend to support the wires once joined.

Thanks!

I crimped mine together and have them in a junction box along with automotive fuse block for power supply to GPS / VHF . Nothing is exposed to the elements !

Some people get away with using normal heatshrink and then filling the ends with glue from a hot melt glue gun before applying more heat to shrink, but it gets really fiddly and the proper glue lined heatshrink isn't much more expensive.

A really good IP67 (or better) case with waterproof cable entry glands can work, but it's more expensive.
