Cecil,
Let me show you what I mean about being specific when comparing antennas.
You spoke of a "simple" dipole that was not rotatable that had a high gain
per Eznec
The dipole I believe was for 10 metres with a lobe gain in the order of 10
db,
you didn't say what the minimum gain was which is crucial when comparing
antennas
So I just designed an antenna with a computor program for 160 metres based
around a patent write up of mine which probably will not be issued until
sometime next year.
The beam is rotatable and is at a height of
20 metres. The max gain is 7.35 dbi at 87degrees. Minimum gain at this TOA
is a few db less. Compared to another antenna, and that is what you are
doing, the gain exceeds a Beverage at any angle over 10 degrees even if the
beverage was rotatable.
Unlike the Beverage the antenna can be used for transmitting. Now my antenna
in the backyard has slightly different dimensions because the material used
was available so the gain is down somewhat and ofcourse the ground is not
perfect.
So Cecil, that is what I mean about supplying relevant data tho perhaps it
would be better if I described the antenna
as a very SHORT dipole.
Cecil you now have a SPECIFIC antenna that can be used for comparison
purposes based on keyboard design that is horizontally polarised

Just remember when Einstein said, "God doesn't roll dice", one of the QED
physicists replied that, "Not only does God roll dice, he rolls them in
the dark." :-) What's wrong with your browser?
