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.
