BTW, Tony Preedy G3LNP published an article last year in QST which
had a loop with variable reactance and resistance termination, by
varying the reactance one could adjust the vertical angle of the main
lobe.

If_I_recall_it_correctly this design uses the *backside* lobe of the K9AY for vertical beam steering which is as we know a lot, 20dB-30dB,even weaker than the low gain frontside lobe.
