When you put them 90 degr. to each other (for example E/W and one N/

both off-resonance to get 90 degr phase time shift in generated fields
(or use a 90 degr. phase shifter and feed them separately).


Hi Wim,

You can do it with a goniometer. This antenna was first described 103
years ago by Bellini and Tosi.
