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.

Ladderline doesn't adapt well to coax interfaces.

What's the best way to put ladderline to my balun coax fitting?

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

I guess I could also stick one side of the ladderline in the center hole of
the chassis coac fitting, and clamp the other side to the threaded part of
the chassis fitting.

Ideas solicited.
