I have finally decided I want a motorized setup for fta, instead of firing up the birodog and reaming all the time when I want to play.. Does the motorized dish M-1 Motorized CLASSIC Blind Search Choice Set: need a serarate power cable or does it get powered off the coax cable 13/18 volts????? I no longer need my superdish thanks to echo 10 spotbeams now , I have a place to put and fta setup.
