Just put up a coax-fed Windom antenna and have about 15-20 feet of
excess coax. I'd prefer to keep the overall length of the coax, just
not sure if coiling it or laying it out flat would be better. I know
the older Windoms needed a tight coil of coax near the antenna, but the
1:1 balun in this
If it were my station, I would wrap it around a 3 to 4 inch form and
lay it behind the operating table. That would further limit RF noise
and would do no harm to SWR.

Hi, Chuck. Since that is just about the exact dimension for a choke
balun from the original Windom design, would it have any effect on the
impedance? I suppose I could just wrap it up and see for myself, but
thought I should at least be nice enoough to respond, since you took the
time to

Very little. It is a fairly broadband 1:1 transformer at HF frequencies and
it forces the currents in the center conductor and shield to be equal.
The amount of power lost in such a choke balun is very small compared to
the power delivered to the load. See The ARRL Antenna Book 21, 26-21
