Thank you for your reply
True any thing directly from a vendor is suspect, but when it resounds so
directly to vertical theory, then it should be respected.
Although I do not claim to be an expert, I chose the link as it put the
information printed in the ARRL manual, various white papers and so forth in
the most understandable format.
I respectfully disagree with your comment. Others may be able to confirm
seeing the Q rising as radials are increased along with other points being
made.
Thanks again and Best 73's

Hi Rich,
Actually nearly all of that is not true as a rule. I'd never rely on a
manufacturers web page for critical antenna information.
