I'm fairly partial to one made by Budwig. I know RF Connection carries
them in stock. I think they are about 7 bucks or so.
It's a one piece molded insulator out of a green fiberglass-looking
material with an SO239 and about a #14 solid coming out of the ends. I
then either solder my antenna wire to the pigtail or use split bolt
connectors.
They've held up fairly well, but I have cracked one that was used in an
inverted V configuration with a lot of down force. However, I prevented
another occurance by hanging the insulator by the end eyelets instead of
the center. Only other downside is that the holes in their insulators are
fairly small, but I use about a 3/16" dacron rope with it and it's FB.
Their end insulators are similar material and holes.
Check out RFC at www.therfc.com . The also carry a nifty #13 insulated
stranded copperweld that is tough, fairly easy to work with, and resists
kinking. It's not cheap, but worth a look. I use it on wire antennas
under stress and THHN on inverted V's, beverages, and the like.

Subject: [TowerTalk] Center Insulator
Does anyone sell a good (corrosion resistant) SO-239 to wire pigtail
adapter?
I am looking for a clean way to transition from RG-142 (common mode choke
balun) to the screw terminals on a 155BA.
BTW, this effort is the result of another dead hy-gain BN-86. Only running
an Alpha 78!
