Good idea. Choose your favorite band for your Carolina Windom and wind
an "ugly balun" choke just below the isolator. An "ugly balun" choke
is capable of forcing a common-mode standing-wave current node
(minimum) on the outside of a coax braid just like a trap is capable
of such on a trapped dipole.

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 ...
