So, just talking out of your ass?

Tap water costs ~ $0.001 per pint. Fiji is about 1500 times more expensive

if you have settled on that as a standard connector, you can make a good buy out of 50m of LMR240UF, a crimping tool frame, die set matching the cable/connector, and 10 packs of Amphenol SMA connectors.

You might get both male and female SMA since female will match a lot of handheld radios, and you can make “extension cords” with one end male and the other female, and you can mount the female ones through a hole in an enclosure or feedthrough plate.

It’s also nice to have a few UHF/PL259 and N connectors - invariably you will have some equipment with them.

Then you would be equipped to make exactly the right length cables with exactly the right connectors and known high-quality materials.

You haven’t ever made your own cable?
