Groundplane Antennas at Various Heights
Do not mount groundplane antennas at heights between 0.25 and 1.25 wavelength. At those levels above ground most of the energy will be radiated at angles of 27gr. to 45gr. into the ionosphere
How many radials does the vertical antenna really need?
Another common question is Does it matter if I lay the radi-als on the ground surface instead of burying them? This is a practical consideration because it's often much easier to lay out the radials on the surface
