Terry,
Have you considered an 80 meter inverted L?

To avoid confusion about how antennas work, it's best to call this a
counterpoise, and leave the word "ground" out of it.
Terry,

It takes up little real estate for the radiator, but does require
putting down a ground screen at the base of the inverted L.
If you do not wish to bury 32 radials for a ground screen, consider
using resonant elevated radials. Two elevated
While you design and experiment with a new loop:
Install a reduced size dipole for 80. My rule of thumb, which has
worked for many quickie antennas is to use insulated #14 wire and
close-wind on a 2" white PVC pipe a length of wire that is twice the
length of that removed from the antenna.
Terry what is the size of your roof line perimeter?

I am moving from my current QTH where I have a horizontal loop up about
35-40 ft. that is a bit longer than 1 wavelength on 80. I feed it at one
corner with 450 ohm twin lead connected to a 4:1 voltage balun, then coax to
my rig. I can tune all the ham bands either barefoot to my K2 or KX3 and
6 matches
