Gary, The vertical monopole over counterpoise (or image plane) has the same radiation pattern as a vertical dipole in free space. If I remember correctly, it has 2.15 dB gain over isotropic at the maximum. Brent DeWitt

(No - I'm not much of an antenna guy). Just trying to figure out a little about the shielding integrity test for e-fields in Mil-std- 285.
