Your range will vary depending on terrain and conditions.

In flat, open country your radio will operate at maximum range.
Buildings and foliage in the path of the signal can reduce  
the range of the radio.
Dense foliage and hilly terrain will further reduce the range  
of the radio.
On FRS Channels 8 through 14, your radio automatically switches to low power, 
which will limit the range the radio can communicate.

Remember, you can achieve maximum  
range by using maximum range extender.
