I remember the Slinky's being copper plated. I wonder if the skin depth lowered
losses on 160 meters.

I have a drawer full of slinky's the steel version. I recall that
someone was making slinky beverages for people that could not stretch
out 300 plus beverages. I never got around to making one. Maybe the
slinky's are collector items now and I can get my money back! HI!

A bad idea when the Slinky is steel. Helical wound copper wire antennas
do work, for TB we used a wound vertical on a FG pole at H40TT.
It was amazing to me that EZNEC will auto generate a helix wire of
arbitrary dimensions, pitch, and segmentation.

Okay then, who was making dipoles out of slinkys? Barbed wire is not
germane to a discussion of either accordion inductors or Tornado Tuners.
Back on topic, I re-read K9YC's presentation about 160 meter
transmitting antennas, and it was good to be reminded of so many
things. A fun fact is,
Maybe I will beat W6DGH to this...
WB6ZKK was pushing barb wire dipoles.

When I was a kid, we had a guy WB6ZKK who touted dipoles made of
slinkys. I am thinking some of the same electronic theory and design
must have come into play.
Tree will remember. Long live the old NTS.

I've not heard the term "accordian" applied, but the Tornado Tuner
expands and compresses a coil inside some pvc pipe to change L about
2:1. I have one (split) to tune the full 80m band at the center of an
86ft rotatable dipole. Your choice of Al or Cu coil tubing with a small
Portescap
Wait. There's such a thing as an "accodion inductor"? I thought I knew
everything.
I'll be glad when mowing season is over, too.

Gud to hear Luke, Dennis and Adrian coming through so well, through
moderate QRN. Unusually warm temps here for mid Sep. (
