With any simple dipole antenna, one "side" of the antenna is connected to the center terminal of the coax which runs to the transmitter (let's call this side A), while the other "side" is connected to the shielding of the coax (let's call this side B). Maybe I am oversimplifying this, but... is the side A of the dipole "hot" while the corresponding side B simply passive and not an active radiator? Or are both sides equally radiating the signal, therefore both "hot"? I hope my question makes sense.
