leaving a large amount above the ground. (Short metal lengths can pick up
signals like AM car radio antennas did years ago)
Carl and all,
For safety reasons ground rods should NOT stick out of the ground. If one
Has anybody tried one of these on 160m? Thoughts appreciated.

Ed, Everything depends on the size and type of tower supporting the
wire plus of course the ground system you have in place. Some reports
are that the support structure, if it is metal, is merely excited with
RF and with the feed wire and the tower does much of the radiating.
There has
In places where you can't get an eight foot rod to go down, there are
alternatives. A four foot rod, or driving the rod down at an oblique
angle will add some resistance, but not enough to change much.
Another method is to dig a hole as deep as you can go (two or three
feet), bury a metal plate
I'd ask the question differently. If you have before data, and can
remeasure after you hook them together to get some after data, and
you are trying to advance science, go for it. But otherwise begin

Over the last 20 or 30 years, the military spent many millions of dollars on
research, development and installation of highly directive Beverage HF
receiving systems using large arrays of Beverages. The largest HF Beverage

To amplify. This will go up on a 70' tower with lots if top loading. AD
recommends putting it at the top of the tower.

On a 70' tower with lots of toploading Ii just don't know why you don't
just shunt feed the tower and have a higher performance TX antenna.
Even connecting a slant wire near the top and feeding it at the bottom
is IMHO a much better compromise. In fact several broadcast consultants
