3.2.7 Other precautions
3.2.7.1
Condensation and water intrusion
If possible, install the radome such that direct spray of seawater is
avoided. In some weather conditions there may occur condensation
inside the radome. The drain tube is designed to lead any water
away from inside the radome. Make sure the ADU’s drain tube is
open and that there it free space between the drain tube and the
mounting surface so water can escape and there is ventilation for
the ADU.
It is recommended not to use pneumatic tools for cleaning the
radome, especially at a short distance and directly at the split
between top and bottom.
3.2.7.2 Deposits
Do not place the ADU close to a funnel, as smoke deposits are
corrosive. Furthermore, deposits on the radome can degrade
performance.
