For the
motorized system to work, the rotation axis of the motor needs to be pointed about 2/3 of a degree higher than the north pole, ie almost parallel to the earth's axis. To do this, it is MUCH easier if you have the motor mounted on a plumb pole. You can get by with a pole that isn't plumb, but it can't be done with a pole that is horizontal. So I'd recommend replacing that right angle pole the dish is attached to, and just use a straight vertical pole.
Then, however, since your mounting bracket comes in from the side instead of vertically, your dish will be sideways using the bracket you have. You might be able to get by with a single lnbf dish this way, although H/V would be reversed, but with your 2 lnbf system, only one would work, plus I'm not sure that you could get much arc before the dish or lnbf arm hit something when mounted sideways. So I'd recommend getting a bracket, such as the pole mount or U-bolt bracket the
Sadoun sells. You could make one, but the bracket needs to be able to tilt to give your proper declination, so it's probably better to purchase one.
