If L-band antennas are installed on the same vessel, keep a minimum distance of 3 meters
from the SAILOR XTR Ka ADU to the L-band antenna.
The following figure shows the minimum recommended distance to other transmitters in
the frequency range below 1000 MHz.
2.2.5 Condensation and water intrusion
In some weather conditions there may occur condensation inside the radome.
1. If possible, install the radome in such a way 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 from inside the radome 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.
