Avoid routing the antenna cable near other cables such as power cable,
transmission antenna cables, or radar waveguides. Close proximity to such
cables could cause interference (electronic “noise”) whereby the signal to the
receiver may deteriorate.
Criteria for site selection
(a) The distance from the magnetic compass should be at least 1 meter.
(b) The length of the grounding wire should be minimized.
(c) The installation location should be as free as possible from direct sunlight.
(d) The installation location should also be: free from excessive heat, moisture, and vibration; in
case of installation on the ceiling, free from the stagnant heat as well as the above, and; in case
of installation near a window, free from salt water spray as well as the above.
(e) The clearances as shown in the figure below should be confirmed.
The antenna cable, power cable, and grounding wire should be routed so as not to be in close
proximity with transmitter, radar, and other sources of electronic noise, as well as the cables of
these external units.
