I have used a G5RV (+/- 51') with ladder line using teflon 24ga silver
plated wire.
also see http://udel.edu/~mm/ham/randomWire/ ... I am working on a 9:1
and looking at the web site, a 70' wire should work fine for 80m...

Hi folks,
For 40m, 30m, and 20m, the KX1 docs recommend a ~24' length of
sorta-vertical #24 wire with shorter counterpoises as a good field antenna.
I've set that up for my KX1 and KX3, and (unsurprisingly) it works well on
both.
For 80m, the KX1 docs recommend a resonant antenna, and I'm considering my
options. Most of what's written out there about low band antennas seems to
be about durable (and heavy) mobile or home installations. Does anyone have
any experience they'd like to share with backpackable lower band antennas?
Options and questions I'm considering include:
* Build a coil big enough to load up my 24' vertical on 80m, with a tap for
60m. Will that be a long enough radiator?
* Figure out the kite-vertical thing, fly a wire close enough to l/4 that
the KX1 can tune it. How bulky would that be?
* Will #24 wire be a decent radiator for the lower bands, or should I eat
the (not-inconsiderable) weight of a bigger gauge?
* Does anyone have any tips on constructing backpackable (minimum weight)
coils? What's the smallest wire and lightest insulator?
* I'm planning a vertical, as this would seem to require strictly less wire
and coils than any dipole or inverted vee, but am I missing some other
offsetting advantage?
Cheers,
Bruce
