Dear Friend
As you know some kind of TV antenna rotate by a rotor .the rotor power is supplied by Main antenna wire (the wire that carry sound and image signals).I am looking for a circuit and description to make a board for this problem. How should you lead me?
It will be appreciated if you could direct me to a correct way
It depends on what type of motor the rotator has (AC/DC/Voltage?), what kind of limit switches there are?, and what kind of rotation position sensor (pot, pulse?) it has.

There are antenna rotators made that send motor power and directional signals through the antenna RF lead. But it's unlikely that you will find a circuit for this published anywhere since these tend to be proprietary.

Indeed, he asked about TV rotors and my answer was skewed by my experience with TX/RX antennas (where this would be unthinkable). Clever that they are doing that now.

i am going to make an antenna with a rotator that rotator(for example a dc rotator) should supply by antenna wire.it means RF signals and dc power signals are moving through antenna wire.
its simple the rotor supplies by dc power.one way is mix a dc power and RFsingnal at first and filter dc signal in the last. i am looking for best way and some circuit if you know.
