Chapter 2: Installing the system
The presences of S-band radar(s) are unlikely to cause any performance
degradation – as long as the minimum distances (d min.) listed in the previous
section are applied.
It is strongly recommended that interference free operation is verified
experimentally before the installation is finalized.
Caution!
Other Inmarsat systems
Recommended minimum safe distance to other Inmarsat antennas is 10 m.
GPS receivers
Good quality GPS receivers will work properly very close to the antenna -
typically down to one meter outside the main beam, and down to a few meters
inside the main beam. However, simple GPS receivers with poor frequency
discrimination could be affected at longer range (typically 10 m). It is always
recommended to test the GPS performance before the installation is finalized.
Other transmitters
See Minimum distance to transmitters. on page 111 in Appendix B for minimum
recommended distance to transmitters in the frequency range below 1000
MHz.

Other precautions

Do not place the antenna close to a funnel, as smoke deposits are corrosive.
Furthermore, deposits on the radome can degrade performance.
14
The antenna must never be installed closer to a radar
than "d min." - even if experiments show that
interference free operation can be obtained at shorter
distances than "d min." in the previous section.
