WARNING : The safety distance from the LT-3130 Antenna Unit, is 0.1 m (0.3 ft), in order to comply
with the regional regulations.
IMPORTANT : Due to the adjacency of the Iridium and Inmarsat frequency bands, the LT-3100 Satellite
Communications System may not co-operate in the proximity of active Inmarsat
equipment.
The LT-3130 Antenna Unit must be installed outside the radar main beam. Typically, this is in the order of
20 degrees. To avoid near field antenna coupling, a minimum distance of 2.5 m (6 ft) between the radar
antenna and the LT-3130 Antenna Unit must be obeyed. Figure 12 is illustrating how the LT-3130 Antenna
Unit should be mounted to avoid interference from radars.
IMPORTANT : Failing to obey the specified installation conditions will void the warranty. However,
depending on the specific radar frequency and power level, the separation distance
between the radar and the LT-3130 Antenna Unit may be reduced, with no impact on the
antenna performance. The performance of the LT-3130 Antenna Unit should be validated
when the LT-3100S GMDSS system is installed.
