I had to chuckle over this -- Art being critical of another antenna
design because the designer doesn't produce adequate quantitative data
or explain clearly what its advantages are.

Thanks for the entertainment. I need a break from reality once in a while.

Would hams have an interest in a two element 20 M
antenna that have lower TOA than the norm, say 9 degrees instead of the
normal 14 degrees?
I think I can quickly put one together for the week end while putting the
present assembly aside.

The gentleman has his patent.
If I disclosed how this could be beat on this forum would I still be able to
get a patent for myself if I so desire? Or would it be best to not disclose
it at all?
I could not see or define the advantages from what I read which is why I
placed the posting.
Absolutely nothing wrong with that Roy, you must be losing it.
Actually I have heard the same thing said of your computor program
instructions

I am no lawyer, but from what I have always heard, if you express a
general idea, that isn't a problem. However, if you are specific, or
offer enough information that someone else can reproduce your idea,
you could lose it.

i.e. 'Modifying the antenna so the angle of radiation shifts several
degrees will improve it considerably' wouldn't hurt your patent idea,
but 'Add a coil at the end with three cw turns overlapping twelve ccw
turns to improve the gain' could jeopardize your patent, or at lease
risk someone racing you to the patent office with an application.

The rules vary somewhat, it seems (I'm not a lawyer either).

Most of the world uses a "first to file" priority rule. Disclosing an
invention before you file, would give someone else the ability to file
for the patent first, and you'd lose.

The United States uses a "first to invent" rule, so in theory the
original inventor has priority even if the invention is disclosed
before filing. Winning the first-to-invent battle can be difficult, I
gather... to prove priority the original inventor would need to have
proof of the date of the discovery. The usual way to do that is to
keep an engineering notebook, date and sign each page and have the
signatures witnessed and/or notarized.

If I recall correctly, there's a limit to the amount of time that the
"first to invent" rule can protect you... one year from the first
public disclosure, I think.

You have up to one year to file for a U.S. patent after you publicly
disclose the invention. (This isn't generally true in other countries.)
I assume that Art would be aware of this since he's been through the
process several times in the past. It's also easy to find at the USPTO
website.
