D. COAXIAL ANTENNA CABLE ASSEMBLY
Refer to Figure 804. The Iridium SATCOM System Coaxial Cable is an RF Cable
designed to cover the frequency range from 1565 MHz to 1626.5 MHz for Iridium
transmit / receive operations and GPS reception. It is a low-loss, aircraft-grade cable
that will be mounted in the aircraft fuselage. This cable provides the interconnection
between the Iridium SATCOM System Satellite Data Unit and the Iridium Antenna.
The Coaxial Cable has an ARINC Size 5 coaxial contact installed on one end and a
TNC male connector installed on the other.
