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

When a 1/2 wave vertical is about 1/2 wave off the ground you get your best radiation pattern without extra lobes, but
if you were to put it on a tower, several wavelengths high, you get multiple lobes. My question is how can you
keep a clean radiation pattern when you are several wavelengths high with a 1/2 wave antenna? Can you put a ground
plane 1/2 wave below the antenna to keep the clean pattern?


create a half-wave dipole and mount it vertically.
