When I setup an antenna in EZNEC, I want to see the azimuth but the

been randomly using 5 or 10 deg.

Thanks

Hi Buck, Antennas have a 3-dimensional pattern. When you only want
to see the Azimuth, you are looking at a 2D pattern, with a fixed
elevation angle. The Azimuth plot must have an elevation angle to have
meaning. The elevation angle you use depends on a number of factors.
For instance, if you want to work dx, or want to hit a distant
repeater, you want the most gain at low elevation angles. You want the
Azimuth pattern to show the most gain at low elevation angles. I think
5-10 degrees qualifies as low angles.
EZNEC shows on the elevation plot the angle where the gain is
maximum. It also has a 3D plot that really gives a good indication of
where you are squirting the most signal.
