What it typically is measuring is the signal-to-crud ratio, where crud refers to both noise and ghosts (intersymbol interference). If you have a lot of ghosts, you will have good spots and bad, as you note by moving your antenna. Listening to FM radio in the car, this shows up as "picket fencing" and "stop light fades."
By the way, what kind of antenna?
