For each location, the maximum achieveable range depends mainly on terrain around the location. Anyone can very easily determin this for his location by method described in the FIRST POST of this thread
What is the Maximum Range I can Get?
Once you know what maximum you can get, you can compare it with what you actually got. If there is big difference, then it may be because of:
-
Your antenna is surrounded by tall obstructions such as tall trees and/or buildings. Raising antenna above the height of these obstructions so that it can “see” the horizon will improve range.

If your antenna is above the height of obstructions and can “see” horizon, and you still have a range less than maximum possible, then you need a better antenna. Adding an amplifier may help.
