Have you ever wondered how far your two way radio will be able to reach?
Use this calculator to find the maximum distance you will be able to cover with your gear.
Enter the height above ground for each of the radios.
This calculator uses the Radio horizon to find the maximum distance covered by a two-way-radio.
Two radios that are 6 feet above the ground will be able to reach a maximum of about 11 km or 7 miles.
Note that this estimate assumes there are no obstructions such as buildings or large structures that block or attenuate the radio signal strength
