 Range 

•

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.
