FURTHER INFORMATION
Talk Range
XTN446 radios have been designed to maximize performance and
improve transmission range in the field. It is recommended that you
do not use the radios closer than 1.5 meters apart, to avoid
interference.
Talk range depends on the terrain. It will be affected by concrete
structures, heavy foliage and by operating radios indoors or in
vehicles.
Optimal Range
Medium Range
Optimal range occurs in flat, open areas with up to 5 kilometres of
coverage. Medium range occurs when buildings and trees are in the
way. Minimal range occurs when dense foliage and mountains
obstruct the communication path.
