Dave,
Go with a a balun designs ( balundesigns.com ) 1115d with the studs on
top. Go from the balun studs to the element halves with a length of
wire and ring terminals crimped/soldered.
For mounting the balun to the boom order the BMP1 balun mounting plate.
Nice and easy and clean, no tape needed other than attaching the coax to
the boom.
I just replaced a F12 balun (cal-av labs I believe) on my C31. This was
the 3rd F12 balun to fail. They short out for some reason. JK Antennas
who now builds F12 antennas also uses Balun Design baluns.
Every one of my antennas now uses a 1115d balun and not a single problem.

I want to replace the 12 turn coax balun and coax on my older Cushcraft 2 el
40. Has anyone used the balun from the later XM-240? I don't see a rating on
it and might look for a 4 or 5KW balun (1 to 1). Anyone used another balun
successfully on the beam? If so I am looking for one with wires to hook to the
driven element center and has a coax connector on the side that goes to the
shack. I also need to know how it is held on the boom. I plan on using tape to
hold the balun on top of the boom.
Thanks in advance for the help.
