Hello,
I agree with Bob, Just read what they say.(carefully)
I'm sure it will work a lot better than just sticking a single
50" whip in the back of the FT817 with no tuning arangement,

I used a "Slinky" antenna running QRP CW from an appartment a while ago.

Re: Slinky Spring Dipole.
I could never get slinky antennas to do that well in field operation using
QRP. Also, they droop. To cure that in the dipole configuration, you need a
slinky bra.

Slinky Spring Dipole.
Has anyone use the "Slinky Spring" dipole (CQ - December, 1980)
with the FT817?
If so, comment/criticism appreciated.

"exhibits remarkable DX performance for a 50-inch whip on the FT-817"
I suspect it works *every* bit as well as any other 2:1 VSWR / 50 inch
