Does seem odd -- I have had very good luck with the balun kits -- basically
just a length of teflon coax and beads -- sold by the Wireman. I use
Budwig HQ1 center insulators, put a PL-259 on each end of the balun, and
use a big tie wrap looped over the insulator and taped to the balun to help
hold the weight of the feedline. I have had 4 of these on my 80m array for
years with no failures. At ~$7 for the insulators and ~$8 for the balun
kits, it's hard to go wrong.
