But I do like all kinds of Slinky Antennas - iane ~ RHF
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
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.
