You're absolutely correct.

The gain at one-half wave spacing from the reflector is *zero*, not zero dB (relative to a dipole), nor zero dBi. As expected from the simple mirror image model there is complete far field cancellation in the phi = 0, theta = 0 direction. That is the only direction referenced in the figure. 73, Gene W4SZ |
