Bryan,

As others have pointed out, the "I" is for isotropic, a theoretical radiator that sends the same signal in all directions. A 3-D model of the radiation pattern would be a sphere. The far field of a dipole has no signal off the ends, and hence has gain in the favoured direction (at right angles to the dipole). The 3-D model would be a donut (without chocolate frosting).
