Below are two models of the 2 meter Quad that BJ posted in his post #12 above. See his link that was produced by HamUniverse.com.

1. is in Free Space and one is over Eznec's idea of Real Average Earth.

2. is a Real Earth model, and is set at 1 wavelength above ground at 146 MHz. I did the model to the specs and got pretty close to their posted results.

I will scale this model to 27.205 Mhz, tweak it as necessary and post the dimensions.

I added the model in Free Space since the article shows us results in FS. I also posted the Real Earth antenna patterns showing both the forward gain and angle, plus the rejection noted at the reflector as negative gain and angle...for those who are interested in rejection.
