Sigh. The inclination degrees are stamped on the dish clamp. Satellite dishes COME with an itty-bitty compass.
All you "need" is a level for getting the mast perpendicular to the ground. Damn kits may even come with that!
The biggest mistake the home installer makes is believing a satellite dish is like a TV antenna and needs to be mounted on the top of a two-story chimney. The difference between 25,000 miles and 25,000 miles minus thirty-five feet is zip! If you can point the dish, unobstructed, at the southern sky, you're golden.
Mount the sucker on the wall, where you can reach it! If not for alignment, then think snow removal.
Geeze.
