Installing the transceiver
● Antenna installation when using a fixed station
For use in an outdoor setting, there are omni-directional antennas and a variety of
directional antennas.
• Omni-directional antennas such as the GP (Ground Plane) antenna are suitable for
communications with a local station or mobile stations in all directions.
• Directional antennas such as the Yagi antenna are suitable for communications with a
specific station or a remote station in a specific direction.
Cautions
z Create a loop (slack) in the coaxial cable directly underneath the antenna and fasten the coaxial
cable so that the weight of the cable does not pull on the antenna.
z When installing the antenna, take into consideration the securing supports and how the guy wires
are positioned, so that the antenna does not fall over or get blown away by strong wind gusts.
