The Customized Antenna Cable Jumper Kit contains the parts required to connect a fixed mast antenna to the Iridium satellite phones or docking stations using a compatible cable (sold separately).To be used in conjunction with Fixed Maritime/Mast Antenna for indoor and maritime fixed installations. The Iridium Customized Cable Kit SKN6121B listed here replaces part # SKN6121A.
This kit, when used with an appropriate Iridium Main Antenna Cable, is designed to connect an Iridium phone to the Fixed Mast Antenna or similar antenna.
Antennas mounted in fixed installations can be exposed to lightning strikes in certain environments. Although it is not possible to protect the Iridium phone, the antenna, or surrounding and/or connected equipment or structures from damage from a direct lightning strike, you should implement appropriate protection to minimize damage to equipment and structures and to prevent bodily damage from lightning. Such protection is typically provided by incorporating a specialized lightning/surge suppressor like the one included in the Customized Cable Kit. Install the suppressor at either of the following locations:
Install and ground the suppressor according to the installation instructions supplied by the suppressor manufacturer. If you use antenna cables from an alternate source, you should still incorporate a device into the antenna cable system to provide protection from lightning strikes and power surges.
The Fixed Mast Antenna is a helical antenna contained within a weatherproof housing. It is intended to be mast mounted without any type of ground plane. For proper performance in the Iridium System:
Any cable solution must have a 50-ohm impedance and must meet the "3 dB" Iridium system performance requirement. Specifically, the total insertion loss for the entire cable run (including jumpers and any lightning/surge suppressor) must be less than or equal to 3.0 dB over the operating frequency band of 1616 to 1626.5 MHz
The insertion loss of the Custom Cable Kit is approximately 1.5 dB. Iridium offers an 8-meter "main" cable (C2-NMNF-8M) that has an insertion loss of approximately 1.5 dB. Together, these cables yield an end-to-end solution that meets the "3 dB" requirement. Alternatively, you can purchase custom cable lengths.
When installing the cables, follow these guidelines:
Note: A bad connection may corrode, causing performance problems.
We also offer Iridium Custom Cable Kit for Fixed Antenna- 10 Meter, that includes 8-meter main cable for use with the Customized Cable Kit.
