If you're only interested in 80m, get a good split stator loop tuning
capacitor and put it opposite the feedpoint in the loop. Make the loop
out of the fattest conductor you can find.

It'll basically be a big halo antenna for 80m. (maybe you could call
it a magnetic loop.. i don't know if people ascribe a particular
fraction of a wavelength limit on magnetic loop sizes)..You'll need a
motor drive for the cap, because as modeled with 3/4" copper tubing and
3-j1200 ohms opposite the feedpoint, the 2:1 SWR bandwidth is about
15kHz.

Radiation resistance is 1.85 ohms or something like that, so you'd need
low loss connections for all the wires and a welded capacitor... if
you do it all right, though, you'd have a good efficient radiator for
local communications.

Just a thought.

I think this would give you better performance than trying to
inductively load the legs.
