So Tom,
Am I reading your data correctly, I see only a 9.7 dB difference as the loop
is rotated from broadside to inline with the vertical source in the first two
columns of A and B. Or am I missing something? My Eznec models of loops show at
low angles a near perfect null for vertical polarized signals broadside to the
loop and a near perfect null for horizontal polarized signal inline with the
loop? As in your A and B tests .

Some of you have mentioned in the past about using a tuned loop for tracking
RFI. A question has sometimes arose about the direction of the null of the
loop. Larry Benko, W0QE, and I did some polarity tests using various
orientations of both the transmitting short dipole and a receiving loop and a
receiving short dipole. The results are shown here:
