Hi everybody, my prime focus dish is installed on top of a motor (Egis, Nitec in past years) that is great but doesn't perform any inclination adjustment when the dish movesto East or West. Just 2 movement: azimuth and elevation. So, until now I used mechanical polariser to set skew for each satellite. Now I would like to replace my old polarotor with more modern universal LNB but my problem would be skew. What about motorizing it? My goal is to find a good little DC motor to rotate entirely feedhorn/LNB block on itself by 180 degrees to set skew remotely from my home, as we make during first dish setup (we rotate the LNB looking for maximum signal before hard screwing bolts). I need a little and slow motor to perform a fine skew tuning, perhaps having a pulse option to use a normal positioner to control it. If not, a normal DC motor with manual control would be OK. And obviously I need mechanical parts to maintain LNB exactly focused on the dish when rotating it, to avoid signal loss. Probably I must build something on myself.... Any opinion and idea would be very appreciated. Thank you.
