21 | Installation and Mounting
NOTICE
Due to the adjacency of the Iridium and Inmarsat frequency bands, the Alphatron
LT-3100 Iridium 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 9 is illustrating
how the LT-3130 Antenna Unit should be mounted to avoid interference from radars.

NOTICE
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 Alphatron LT-3100 Iridium is installed.
The LT-3130 Antenna Unit shall me mounted minimum 1 m from MF-HF, VHF, and UHF antennas.
