Simple! All depends on the terrain or the location of your transmitter.
In a big city, we can talk from 3 to 6 Km. In a city with a repeater on a high mountain, we can put our signal at more than 20 Km. And in a flat terrain without any obstacles, but at the normal human heigth, no more than 6 to 10 Km.
