From here: http://en.wikipedia.org/wiki/General_Mobile_Radio_Service#Range "As with other UHF radio services, reliable range is considered to be line-of-sight and the distance to the radio horizon can be estimated based on antenna height. Theoretically, the range between two hand-held units would be about one or two miles (about 1.5–3 km); mobile units have higher antennas and a range of around 5 miles (8 km). A GMRS repeater with an antenna that is high above the surrounding terrain can extend the usable range over a wide area – for example, up to a 20-mile (32.2 km) radius around the repeater station.[6] Obstructions such as hills and buildings can reduce range. Higher power does not necessarily give a proportional increase in range, although it may improve the reliability of communication at the limits of line-of-sight distance."
Sorry, there was a problem. Please try again later.It says 30 miles on the box. I’ve only tested to about 2 miles, but they go that far without any problems.
Sorry, there was a problem. Please try again later.A mile and a half if youre lucky
