Got a Radio Works choke balun I'd like to use for feeding ladderline out of
an unbalanced tuner.

The balun has coax fittings on each end.

Sounds like it is actually a UNUN.

I can kluge a PL-259 plug onto the ladderline.

That will work. I usually just splice a short piece
of coax to the ladder-line.
