Condensation, water intrusion and deposits
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.
Observe the following guidelines for condensation and water intrusion:
1. If possible, install the radome such that direct spray of seawater is avoided.
2. 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.
3. Do not use pneumatic tools for cleaning the radome, especially at a short distance and
directly at the split between top and bottom.
4. Do not place the ADU close to a funnel, as smoke deposits are corrosive. Furthermore,
deposits on the radome can degrade performance.
