Hmmm .. not a balun fan in the first place, but .. have a BN-86 up on my 
"tower" ... RadShk chimney-mounted mast -- been up 12+ years now, used 
1Ø/15/2Ø//4Ø perverted vees for "guywires" -- had just fixed a BN-86 for 
whatever reason, and just clamped it to the mast "because it was there" ... fed 
it with 4-1ØØØ, SB-22Ø, etc... mostly barefoot, though ... has made THOUSANDS 
of contacts, and still worky worky.   The clue to those aminals is this.  They 
"desolder" themselves.... I put turns of small wire around the funky 
connections at the end of the 14 gauge coils around the ferrite core, twisting 
the ends, making a good mechanical connection.  THEN soldered the connection. 
End of that problem!  Have had problems in the past, frying those critters, 
though .. when in the wee hours of contest, forgetting to turn the aerial 
switch, Henry would give it a shot, and ... kablooooey!   Again .. only reason 
that balooooon up there is it was handy, and my helper (no-ham brother) was 
impatient for me to do the job... been there all these years!   My 75/8Øm 
dipole has no such fuse. By the way, the same method of tying copper wire round 
and round fixed my problem with Daiwa 4 position co-ax switches, too .. if 
stressed by RG-213, 214, 8 .. they tend to become unglued at the SO-239.  73,
