Top hats could be skirts if you feed the antenna through them.
This design looks a lot like a “conical monopole”. Is there a distinction?

long trunk section, and measured resistance.

If I can support a wire antenna at 50' or maybe more in tall pine trees and
have 1.9 acres of space to use which would work best.
Lots of tall pine trees on the lot. I assume the trees in the center of the
square will
Paul,
At least in the copy of your message I received, it was a bit hard to
determine where the frequency ended and the SWR began. As I understand,
the SWR was
1.77 MHz 6.21
1.80 MHz 4.31
1.845 MHz 3.37
1.86 MHz 3.77
1.89 MHz 4.88
1.91 MHz 6.08
1.94 MHz 8.19

Take the tuner away from the source of interference,

I do, however, suspect that because going digital is such an obvious answer
that there must already be some activity among devotees so I would be
interested in hearing what frequencies and what modes are used on 160 meters

I hope everyone has the correct info now.

I have a good friend who has a 1/4 wave 80 foot vertical (63 feet) who
decided to put a 100 foot coil to bottom feed the antenna for 160M. Using a
