Install protection such as a simple roof above the Level Meter to avoid exposure to direct sunlight.

・

There is a structural equipment that the cone antenna goes out than the attaching portion when the
horn antenna is detached by maintenance etc.
Please do not put the cone antenna part doing below after detaching the horn antenna.
The cone antenna might be damaged, and it influence the measurement.
