If I did everything I promised to do, I'd never get anything done.

There's always time to do it over again after a rush job.

I found a better biquad model at:
http://pow.za.net
that compiles quickly, is much simpler, doesn't require wavelength
scaling, is vertically polarized, and is much simpler than what I
previously posted. I re-ran the 4NEC2 model and dumped the output at:
http://802.11junk.com/jeffl/pics/antennas/Biquad/
The NEC2 file is at:
http://802.11junk.com/jeffl/pics/ant...biquad.nec.txt
Gain is about 11dBi. -3dB beamwidth is 60 degrees horizontal and 50
degrees vertical.

You can download the 4NEC2 program and sample antennas from:
