3.3. Draining Holes
There are two draining holes inside the housing at the bottom left- and right corner of the antenna.
These holes are used to guide condensing water out of the outer circle of the housing.
NOTE:
The protection class of the antenna is not affected by the draining holes. The blocking that
guarantees the protection class of IP65 is inside the housing.
Water in the outer circle of the housing does not have any impact on the performance of the
antenna.
