I agree with Dave.  We had a similar discussion about this (using monopoles) nearly 20 years ago in the rec.radio.amateur.antenna forum.  I wrote a little paper at the time; I see it's available at:

If you have a proper balun at the feedpoint, there isn't a "hot end."  It's a balanced dipole, until it isn't because one end is closer to the ground than the other, of course. Wes  N7WS On 6/13/2020

Indeed, that's why monopulse RADAR antennas determine angle information using the delta channel nulls. Wes  N7WS One thing you also need to be aware of when working with nulls is that the slope of th
