Ground plane antennas are useful for a variety of amateur radio operations from the upper HF bands (20 meters through 10 meters) to the 6 meter, 2 meter, and 70 centimeter amateur radio bands.

This calculator from Glynn "Buck" Rogers (K4ABT) of BUXCOM (http://www.BUXCOM.com) is designed "to give the vertical length of a quarter wave ground plane antenna and the length of each of the four radials for the selected frequency you have entered." Element and radial lengths will be given in terms of meters, feet, and inches.  Some pruning of wire/rod lengths may be needed to keep SWR below 2:1.  A handy, useful guide for the antenna experimenter.
