Hi Jim & all,|
thanks alot for your help. I'm just trying to write a little bit more detailed document about my experiments with the verticals.
In order to conentrate on the main problem, I didn't tell that my
array was a little bit bigger.
I set up 3 verticals in a isosceles <http://dict.leo.org/?p=lURE.&search=isosceles> triangle <http://dict.leo.org/?p=lURE.&search=triangle>. At any time I'm using
two 2 verticals. This gives me 6 directions.
I can supply more informations (pattern, NEC files, messurements,
but let me just quote your comments:
Close in contacts (or two bounce contacts) will have a high elevation angle,
Right. Anyway, I should have in *all* situations more than 6dB f/b ratio. (according to the antenna pattern)
Right now I have two possible answers / questions:
Yes, of course. I made two switching boxes: 1. 2el Array (2 switchable directions + single vertical) 2. 3el Array (6 switchable directions)
