First, consider the cable. I make my living using coaxial cables with
BNC (and other) types of connectors, and I can't count the times that
those connectors have failed. True, some were due to poor assembly, but
others (that had been tested after assembly) failed during non-abusive,
normal service.

Having made up, though not professionally, a few BNC terminated co-ax
cables I'd emphatically agree about some connectors being the weak link:
especially the solderless, no-crimp twist-on BNC connectors. I mean the
type where the centre wire is just pushed into the centre pin and the
ground is a knurled cylinder that you're expected to ram between the
braided shield and the insulation.

I've had uniformly bad results with these connectors and, as the
connector can be easily pulled off the cable, they're probably wildly
unsuitable for an ELT antenna cable.

I will go out of my way to find a soldered-on BNC connector: I've not
tried crimp-on types.
