2.2.8 Other precautions
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.
Deposits
Do not place the ADU close to a funnel, as smoke deposits are corrosive. Furthermore,
deposits on the radome can degrade performance.
