1Introduction
The Alphatron LT-3100 Iridium is a maritime satellite communication product. The Alphatron LT-3100
Iridium is designed for the professional market (deep sea, fishing, and workboats), but can be used
for the leisure market as well. The Alphatron LT-3100 Iridium meets all standards and certification
requirements needed for worldwide maritime satellite communication equipment.
The Alphatron LT-3100 Iridium has voice and data capabilities with 100% global coverage provided by
the Iridium® Communications Network. The Alphatron LT-3100 Iridium consists of a control unit,
antenna unit, handset, and cradle. A single coaxial cable connects the control unit with the antenna
unit. Using a standard coaxial cable, up to 500 meters of separation between the units can be
obtained, giving freedom to mount the antenna unit in the best possible location, with free line of
sight to the satellites.
The Alphatron LT-3100 Iridium can be used as the primary satellite communication product on
vessels, covering the basic communication needs in terms of connectivity between the ship and
shore.
