Explanation
Inside Car /
   Inside Car
Average < 1/2 mile
< 1 km
Your car is a metal shield
 Radio/Radio Metro Area 1-2 mi
2-4 km
Based on obstruction and buildings
 Radio/Radio Suburbs 3-5 mi
5-8 km
Based on the amount of leaves on trees
 Radio/Radio Flat Desert or
Over Water
5--10 mi
8-16 km
Based on line of sight to the horizon
 Radio/Radio Mountain to
Valley
10-15 mi
15-25 km
Based on height of mountains and terrain below.
 Radio/Radio Mountain to
Mountain
25-30 mi
40-48 km
Based on height of mountains. Possible, but definitely not typical.

 
Elevation and obstruction are the two key factors in determining expected distance. A better antenna will also increase the range of your radio, but remember, there is no 'Magic Antenna'.
 
 
 


Your elevation and lack of obstructions will determine the overall distance you can achieve.  Trees and buildings are not your friends when trying to reach great distances.
 
 

 
BTW: When you see little 'Blister Pack' radios in the department store advertised as 18/30 miles between two radios, they are talking Mountain to Mountain or through a Repeater. There are No magic radios out there. Refer to the chart above.
