Default Gaussian antenna aunwin

Art,

I looked at your webpage at

http://home.insightbb.com/~aunwin/index.htm

I don't understand how you claim that all three elements in your
cluster are resonant given that the drive impedance of two of them is
highly reactive.

Your antenna appears to be a fairly mediocre weird yagi.

You can continue to write science fiction about how radiation is
caused by particles ejected from the conducting material and their
curling action about the element, or whatever it is you're talking
about. Have fun. Sorry if my pseudo-self is going to keep pseudo-
thinking that your antenna is more or less a pseudo-two-element yagi.

The structure, as shown on the web site, has the following parameters:

Gain at 10 deg. elevation -- 10.2 dBi
F/B ratio -- 5.5 dB
Input impedance -- 126 + j 171.

Ball park guess 2 element beam at the same elevation.
Driven element 28", reflector, 29.5", and element spacing 7".
Elements 0.2" dia. aluminum:

Gain at 10 deg. elevation -- 12.3 dBi
F/B ratio -- 12 dB
Input impedance -- 35 + j 38

All above simulations using NEC above a perfectly conducting ground.

Regards,

Frank
