I visited a place of taller hill last time. There are lots of towers of cell phones, AM radios, FM Radios and Televisions. There are two photos of FM's:-
I think "A" antenna is a type of yagi for one side powerful transmission. There are 3 rods to which i marked with red circle. Which is the antenna rod? I think- front is director, middle dipole and last is reflector, isn't it? I hope this dipole length is similar as single dipole!
I've never seen "B" type of antenna. I found it on 10,000 watt FM station. Cannot understand the theory of it, even cannot reconized the rod of the antenna!
Anybody, do you have internal diagram of these antennas and working theory in simple?
