Communication Environment
1. Basic communication environment
a. There should be no other equipment which transmits interference signals
whose strength is greater than or equal to the energy output of the PMR
1420, such as overhead electricity cables, radio stations, etc., within the
communication area.
b. There should be no large buildings with metallic sections or metallic
fixations within the communication area and open spaces.
2. Perfect communication environments
If the two points above regarding basic communication environments and open
spaces are observed and maintained, the communication range can be up to 10
km when the communicating partners are on a horizontal plane.
3. Poor communication environments
If a solid obstruction stands between two communicating partners, it is
recommended that these partners do not communicate under these conditions.
