On page 6-29 it says: " "Experience has indicated that a secrion of wire

would require approximately 230 feet of wire, spirally wound on the
support. *Art may have discovered the above alone but he was very
unlikely to have

I don't have any issues with spiral wound loaded antennas. *I have several
hamsticks which fall in that category.


Perhaps you've missed the parts where he claims performance including gain
and especially directionality from a 160m antenna that is perhaps the size
of a shoebox. *And has windings in one sense and then in the other.
That's the stuff he won't and can't prove works as claimed. *And I just
remembered the part where he's going to put a DSS style dish behind it to
make it even more directive.


And then there's the imaginary physics that he claims makes all antennas
work.


Sorry, I stand on my statements.

oh yeah, i forgot the laser beam pattern... was it also circularly
polarized, or was that some later rant?


Oh come on .you are riding on each others misinterpretations.
Pointless to follow this course. Watch the other thread on Gauss/
Maxwell.
I am sure there is somebody with some smarts that can state
specifically why it is correct or incorrect and just not shoot from
the hip with personal intuition. If the statement is in error then
every thing else falls apart. You don't need a character wipe out now.
The question of mine that is placed is clear and concise and I have
declared ownership of that statement.
