Antenna Unit Unit Installation

At antenna unit positions more than 60° above or below the
radar, it should be possible to reduce “d min. operational”.
It is strongly recommended to verify interference free
operation experimentally before the installation is finalised.
Even if experiments show that interference free operation
can be obtained at shorter distances than the “d min.
operational” given above, the antenna unit must never be
installed closer to a radar than the “d min. damage” given
above.
Other Inmarsat Systems
Recommended minimum safe distance to other Inmarsat
antennas (like Inmarsat B or Inmarsat C) is 10 m.
Other Transmitters
See curves in Appendix C.1 for Minimum Recommended
Distance to Transmitters in the frequency range below 1000
MHz.
Other Precautions
Do not place the TT-3008G close to a funnel, as smoke
deposits are corrosive. Furthermore, deposits on the
radome can degrade performance.
3.3 Unit Installation
3.3.1 Antenna Coaxial Cable
The coaxial cable for connection between the antenna unit
and transceiver unit is not
part of the basic system. Make
sure that a sufficient length of cable is ordered; refer to
Appendix A for selected cable options.
