PMR446 is alicence-free communication standard for use over theFM
frequency range and operates at 446 MHz.
Range capacity is highly dependant upon thesurrounding terrain. Maximum
range is achieved in open unobstructed terrain,e.g. intheabsence of hills/
mountains, buildings,etc. Toavoid interference, theradios should not be
used at adistance of less than 1.5 m from eachother.
