I was looking to possibly set this up on my 12 foot dish. Does anyone have any experience with this setup? I noticed an older thread but it related to the dsr920. Also, do I need a special motor with a position sensor in it for the degree function to work? I know how to hook up the motor but am unsure about the positioning. Also, does anyone have any ideas for a cord to run to this? I need probably 50 feet or so.
