Default Yagi efficiency

Wow Yuri has arrived

I remember that long discusting arguement he had with Tom Rauch
that brought words to the fore that brought shame to amateur radio
I'm gone, I want no part of what is now on the near horizon
Have a great year fellars I enjoyed the short visit while it lasted

I know I was very lucky and have no idea why people
collect those things or enter contests... the noise is horrible I think
I had 13 elements on a 60 foot boom at that time plus a couple of
reflectors to experiment with.


Art,

Why do people run Marathons, race cars, boats, airplanes or turtles? Some
like to walk, some roll in the mud, some like to compete in the stadium.

Contesters like to prove that they can design better antennas, assemble
better stations and prove that they are better operators. It is also real
test for antenna designs and propagation knowledge and how to exploit both
for better results that can quantify the performance and weed out junk and
junk science. It takes years of devotion to show up in the top ten listings.
If you have revolutionary design, we contesters will be first, dying to use
it and cream the competition - that's the real test and not mumbo-jumbo
claims.

BTW I have a "secret weapon" too, it is a ferrite stick in the dish. Very
efficient, no side lobes, one sharp beam, no side or back lobes. It is right
up there with EH, Freaktals and perpetual motion machines.

If you assume that propagation between you and UK is as you describe, you
are way off. We are also ducting, use skewed path and changing angles
depending on the point in the sunspot cycle, sun' activity, etc. etc. So for
optimum propagation one needs either antenna that has wider beamwidth or
sharp and stearable one in H and V planes.

Can you enlighten us about your new revolutionary invention? Is it better
than your patented reflector that is shorter than the driven element?
