Topband: duo-band 80m/160m antenna

[Carl Luetzelschwab]

All,

I had a quarter-wave 80m wire vertical (thanks to a pulley under the limb
of an 80ft tall oak tree) with three elevated radials. Worked great.

I bought a length of 3-inch OD B&W inductor stock and got some high-voltage
door-knob capacitors to make an 80m trap. Put it at the top of the 80m
vertical, added three 120ft elevated radials and added a wire that slanted
back to the house to resonate it on 160m.

it took some extra work, but it was a nice duo-band antenna with my single
3CX800 amp.
