Default Can you put a ground plane 1/2 wave below the antenna to keep the clean pattern?

"Roy Lewallen" wrote in message ...
You would have to create a ground plane that extends many wavelengths from your antenna. The multiple lobe pattern is produced by
reflections from the ground which are far away -- the lower the angle, the farther from the antenna.

Why don't you just lower the antenna to 1/2 wavelength if that's the pattern you want? Then you'll have just the ground plane you
need, the right height below the antenna -- the ground.

Hi Roy:
With 10 meters and above, the higher you have your antenna, the better
the local reception. I like to get above the power lines.
