First off the pole has to be as close to vertical as possible, vertical left to right, front to back.

Then mount the dish and motor to the mast, and check for any sag to the front with the dish and motor mounted, this is important as if the mounting pole sags you will have problems.

The find DUE SOUTH from the mounting location of the mast and dish/motor, make sure the motor is set to ""Zero", to find due South use an app called "dishpointer dot com", enter you location and zoom into it, this will give you a map showing Due South (180 degrees true)from your location, this is very important as the dish needs to line up with the arc of satellites.

Dishpointer dot com also will give you elevation settings for most motors.

Once your motor and dish elevation has been set you can look for the DUE South satellite at your location, this looks to be around 84 west, unfortunately that satellite is a "C" band satellite, so you will need to offset a bit, 81W is the next one, and is viewable at your location, use transponder 11796H, this will be your starting satellite, and would be close the top of your arc,(off set by 3 degrees) all satellites will be to the East or West of this satellite.

I get this from dishpointer, Address: 10.015900, -84.214200
Latitude: 10.0159°
Longitude: -84.2142°

Satellite: 84W STAR ONE D1
Elevation: 78.2°
Azimuth (true): 178.8°
Azimuth (magn.): 181.0°

It looks like you will be elevating the dish and motor to around 78.2 degrees, this would have to be done with part dish and part motor.
