Default Cecil, was it you that mention a "windom balun?"

OK, I'll ask, "I am correct in thinking that most are using a 'voltage
balun' (ruthroff 1:4) as the 'Low Loss Matching Transformer' and a
'current balun' (guanella 1:1) as the 'Special-High Isolation Line
Isolator?'"

I mean, logic dictates this to be the best combination ... however, one is
best to ask ...

That is what I am using on a home built version. Using a 4:1 voltage balun
at the feedpoint and the ferrite bead type about 20 feet down from the
feedpoint.

The ferrite choke is doing something as it gets warm while running around
about 1 KW to the antenna. Doesn't heat up when going into a dummy load.

My 'Windom' usually works beter than an 80 meter dipole on 80 meters plus
gives me the option to operate several other bands.
