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 mainlobe. 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. 73 ClemensDL4RAJ.. ----- Original Message ----- From: "Warren Ziegler" <[email protected]> To: <[email protected]> Sent: Sunday, May 13, 2012 11:37 PM Subject: Re: LF: Cardioid RX antenna for LF... |
