Ron, The FCC regulations for 60 meter power is referenced to the maximum lobe of a dipole. Sooo -- That should be "0 dBd" (gain/loss relative to a dipole) rather than "0 dBi" (gain relative to an isotropic radiator). If my recollection is correct, 0 dBd is 2.15 dB greater than 0 dBi in the dipole's favored directions (perpendicular to the radiator). For those not familiar with an isotropic radiator, it is a point construct in free-space that radiates equally in all directions.
