  • Page 4 b) For V/UHF (6m and above), the counterpoise (groundplane radials) are connected to the ground point bolt near the antenna base and works best if slightly shorter than a 1/4 wavelength. For single band antennas, the length should be "cut" for the band; for multi band antennas cut the radials for the lowest band. These can be made from stiff wire or whip antennas or other radials sticking out from the base of the antenna.
