4-1-3 Rainproofing of Antenna
The antenna is not waterproof structure. So, do not install the antenna.
If you must install the antenna outdoors, protect the antenna against rain with a plastic rainproof box. To prevent the water droplet com-
ing in the antenna through a cable, be sure to turn the antenna cable section downward.
Example of plastic rainproof box: Model WB-5AJ (Outside dimensions: 571 (H) x 571 (W) x 210 (D) mm, Mirai Industry)
Correct Usage
Protective structure IP62 of the antenna is the protection against the drop of water. If the antenna is splashed with water
spray or water jet flow, cover the antenna with a protection plate. (Refer to "Appendix 3 - Protective Structure".)
Gap between the antenna surface and window plate is 10 to 20 mm.
Size enough to cover
the entire antenna
including a connector.
Example of protection box
Drill a large hole for ventilation
and drainage.
Clamp it to prevent the connector
being pulled directly.
If the box is metallic, make
a window on the box. The
window size shall be the
same as the antenna.
Cover the window with an
acrylic plate, etc. 3 mm in
thickness which a radio wave
can penetrate easily.
