Looks like it could stand one more core and one more turn, if I only used
it on 160 and 80.
You must have an old version of it -- the latest is summer
Jim,
Would the type 75 material from Fair-Rite, be a better choice for 160 &
80 with 5 turns thru the 0.75" id clamp on?

It depends entirely on cost of the component. The peak of the impedance
of a single core is in the right frequency range, but a sin
The 0.75" #75 clamp-on is 0475176451 and circa $15. By my connibulations
it'll be a really close squeeze to get 5 turns of RG-6 through there. I
think 5 turns of RG-58 could happen.
The 2.4" #31 core is 2631803802, circa $7 and much easier to get many more
turns of RG-8X through it.

No. I wrote badly. Measure out two 5 feet lengths of enameled wire.
Tape them together (a single wrap of tape every 5 inches or so) and wind
that pair of wires 16 turns around a single core. Connect it at each end
as a two-wire transmission line.

And you would not WANT to wind turns through it -- that would move t
I like to wind these kinds of things using RG400. That's RG58-sized teflon
dielectric and teflon jacket with silvered copper double shield and
silvered copper fine wire stranded center conductor. RG400 is specifically
made to be put in airplane wiring harnesses with all those sharp bends and
