Please, let's never call it just "poly" - if we do, we're setting someone up for an accident. If they buy polypropylene rope by mistake, it stretches almost as much as nylon and degrades very quickly

Agreed. 10-15 years ago, when Heliax connectors were rare and expensive, I spliced two lengths of LDF4-50 using the brass/copper tubing method. This was waterproofed with self-amalgamating tape, and

These are not the best you can buy. They only clamp the cable by trapping the braid, and the braid can still tear out very easily. Also they require the braid to be trimmed and fanned out correctly.
