You need to mount the vertical no more than a very few INCHES above the ground level and run radials out from there. Each radial wire at least 1/4 wavelength, at least half a dozen, maybe more, fairly equally spaced. You can bury the wires in sand with no problems.

If you simply MUST elevate the antenna, you'll have to elevate the radials to keep them close to the feedpoint. You'll still need at least four radials and more would be better (IMO) to act as the return path for the RF sent out by the vertical radiator. The antenna will be more sensitive to radial length than if it were ground mounted. Radials can double as part of a guying system.

Either way, be careful that no people or pets can come into contact with the antenna OR the radials.
