I've read that a satellite's elevation is the angle between it and the horizon from a point where the reading is taken. Since I can't see the horizon, what I'm asking is - if the lower leg of my angle finder is level (about 900 ft above sea level), can I rely on the angle between it and the upper leg in order to determine if I can see the satellite. I just don't want to spend the money and do a pile of work only to discover I can't receive anything.

What i use is a protractor, compass and a straight edge if you have a clear line of sight when sighting down the straight edge set to the sat angle you should be able to receive the sat.
