Range mainly depends upon terrain arround antenna location which in turn depends on geographical location. Incresing antenna height also increses range, if antenna is surrounded by tall buildings/trees/hills. Once antenna is above these obstructions and can “see” horizon in all or most directions, any further increase in height brings very little improvement.
You can find your maximum reach at each of different locations (which you have mentioned in your post above) by method described in the FIRST POST of this thread:
What is the Maximum Range I can Get?
