Art, please fill in the blanks. Trust me, it won't harm in any way your
ability to obtain a patent.

----------

Hi, I'm aunwin. I have invented an antenna that's an improvement over
existing designs, because:

1. The gain of a __[A]__ when mounted ______ feet high is _____ dBi at
an elevation angle of __[b]___ degrees. My remarkable antenna has a gain
of ____ dBi at that same angle.
2. At the same frequency as used to determine the gain in item 1, the
reference antenna has a front/back ratio of ______ dB at an elevation
angle of __[b]__ degrees. My marvelous antenna has a front/back ratio of
______ dB at that same angle.
3. At a frequency _____% [above|below] the frequency of items 1 and 2,
the reference antenna's gain has dropped to _____ dBi and the front/back
to ____ dB. My terrific antenna, however, still has a gain of ______ dBi
and front/back of ______ dB.
4. When matched to 50 ohms at the frequency of items 1 and 2 which is
____ MHz, the reference antenna has a 2:1 SWR bandwidth of _____ MHz. My
outstanding antenna has a 2:1 SWR bandwidth of ______ MHz.


A = the name of a reference antenna having a similar size, number of
elements, complexity, or cost compared to your antenna. In other words,
a common antenna that your antenna is better than.
B = an elevation angle useful for DX work -- choose anything between 2
and 10 or so degrees. It would be best to give gain and front/back for
multiple angles.

That'll show those ignorant troglodites like Roy and Wes that there are
still Galileos out here who can laugh in the gurus' faces and come up
with performance they never dreamed of! You wanted numbers, I gave you
numbers. Choke on those, you doubters!

----------

That's all you've got to do, Art, just fill in the blanks. A few
numbers. No need for expositions on coupling, polygons, or takeoff angles.

Not holding my breath,

Roy Lewallen, W7EL
