from the base of the tower :-)
I'm not saying that extra grounding isn't required or is a bad idea, just that
concrete encased steel isn't a bad idea.

Isn't the tower base pretty much a ground rod?

As a retired 2-way radio tech, I'm aware of two towers that had to be
re-installed because of lightening strikes exploding their concrete bases.
I'll agree with both points.
That said, think about the space between wires. On and about the wires is a
relatively thin layer of plastic. From there, the space between wires is filled
with...wait for it...air.
It might be worthwhile to read this: http://k6mhe.com/n7ws/Ladder_Line.pdf

Why do you suppose a little bit of dielectric on the wire would make a huge
change, when the majority of dielectric is still air?

So, these numbers are for BARE copper, right?

these guys planned to do it in a regular lab environment. I told them that I
would (and did) build the PA, but I didn't want to be anywhere near it during
the testing. I'm glad I wasn't on the carrier deck either.

I assume you're commenting on the 1KW 20' away, although failed to say so. Turn
this scenario around: pretend that you were trying to do medical treatment or
research by heating your body to a biologically significant temperature. How
much power to a transducer 20' away would it take?

I just saw the 4 X 6 antenna on the next to last page.
Thanks for your nice comments.

Nice construction of your projects Wes. Very nice indeed.

If they ran a decent antenna they wouldn't need that power. Interesting project
though.
Here's a couple of amps I built years ago. http://sadxa.org/n7ws.html
