=============
I have a terrific wire-beam antenna that rolls up into a package that
weighs only a couple of pounds. However, it requires one rope into a tree
or other type of sky-hook.

It is good for 20, 17, 15, 12 and 10 and is bi-directional. It's a form of
W8JK, but is fed at the end and has series capacitors in each radiator to
make it work over a 2:1 frequency range. I designed it with EZNEC and I'll
send the model to anybody who wants it.

It's fed with window line and requires a balun at the transmitter. It takes
a good tuner to match it, but the Elecraft tuners can do the job.

Anyway, it doesn't meet Wayne's request for a free-standing antenna, but
it's a cool field-day antenna, especially here in the middle of the country
where a bi-directional antenna is a good thing.
