Does a slinky antenna really work as a compact antenna?
IOW, does it perform as a 64 foot antenna rather than a 15 footer?


IT'S GOOD ENOUGH FER GUMMINT WORK which iirc was where it began , in
Korea, I think.

there was an excellent slinky site now dead that acknowledged it had
shortcomings as a transmit antenna outisde its resonance (7.2 mhz) but
mine went up to 15 mhz as a receive antenna falling off as frequencies
elevated. Above 17.6 mhz it was worthless

I prefer my North county active SWL antenna which on a 10' PVC pipe mast
works BCB to 28 mhz

I got my old 1961 Hercules Moped (made in Germany,it has bicycle pedals
on it) running again.New transmission gasket I made for it,new tires and
tubes.Them two divorced wimmins next door to me immediately adopted my
Moped.Oh well,,, I am too d.n fat and heavy to ride it around anymore
anyway.

The problem with this type is that the current distribution along these
shortened antenna elements will not be correct or sub optional. This is
fixable problem though, which will require more "structure" to solve.
