Hi!
I've leaned that Mechanical downtilting of Antennas may change the form of the main beam, and also unlarge the other beams, but the electrical downtilt doesn't change them.
Also, what I want to know how it is done : when doing an electrical downtilting, the secondary beams will also be reduced down (on the other side), but in mechanical downtilting, the secondary beams will stand up (on the other side).
Does any body know how is this phenomenon done.
Thank's for your help.
