Art,
I am convinced that you are experimenting in an area of antenna

transportation is a problem I will fly my airplane to your area and

I will personally mount your antenna at the top of a 150 foot tower
and we can measure the near field intensity and far field signal
strength developed by the antenna, compared to my normal size antennas
which are off another tower at a distance .. *I am sure I can convince
a few of the regulars on here to be on the band and be ready to
participate with signal strength measurements, spectrum analyzers,
etc... *This would form an excellent basis for an article for you to

If I am not convenient to you then I suspect that W8JI or others would
offer a similar testing range and I still would be happy to provide
transportation just to be a part of an exciting new chapter in radio
experimentation...

I suggest that you take pains to make sure the feedline is well
decoupled - a couple of current baluns, one at the feedpoint and one a
quarter wave down the line, should be adequate. An extra measure would
be to measure the common mode feedline current to make sure it's
minimal. That would go a long way toward silencing critics (like me) who
believe that reported good results from such small antennas are often
the result of feedline radiation -- that is, that the feedline is the
primary radiator and the "antenna" plays only a minor role.

I understand all that. If Tom wishes to add one for his
own satisfaction that's fine by me.
If he wants to test it then I am confident he will do what
ever is necessary without comment from me.
I have no wish to influence him in any way. He cam make his own call
even if it means that it burns up. I have no experience with 180 M
and have only loaded it for 100W. As I have stated before, I have not
been active for years because of illnesses etc and I would not
presume
that Tom would need any assistance from a blithering idiot and
liar such as I.
W8TI Tom laughed his socks off when I mentioned resonant tank
circuits
in equilibrium and refused to give me any time for discussion.
On the other hand, Tom in Michigan has always been polite to me
and appears to have a genuine interest in new ideas, so I have
worked all day today in getting things together so I can get
one to him as quickly as possible.
