Got a Radio Works choke balun I'd like to use for feeding ladderline

I'm sure others here will correct me if I'm wrong, but I believe that
what you want to do is a very bad idea. Baluns are not meant to operate
under the potential very high SWR conditions ...

It depends on whether the very high SWR is on the ladder-line
side or on the coax side. :-)
