One word of advice - Never believe the range claims of a 2-way radio manufacturer.  It may be true that two half watt UHF radios operating without a license (and presumably without interference of any type) can communicate over distances of up to 5 miles IF one of you is on the ground and the other is straight up in the air at an altitude of 26,400 feet.  Be forewarned if you are going to try this in a hot air balloon - take oxygen, and keep a sharp eye out for commercial aircraft.

We don't sell the half watt versions of FRS radios, but we do sell other radios (Business Band, GMRS, and Public Safety band radios) that can be operated as portables with power levels of up to 5 watts.  You can read all about them in the GMRS section by clicking on the tab above.
