Installing Antenna Cables
When you install the cables, follow these guidelines:
•
Route and restrain cables to prevent them from vibrating or moving under
normal conditions, which could result in damage to the antenna, Beam
terminal, or the coaxial cable connections.
•
Wherever the cables contact structures, protect the cables from chafing or
abrasion.
•
When you must bend a cable, avoid kinking it, and ensure that each bend
radius follows the cable supplier’s recommended limits.
•
Use coaxial sealant, shrink-wrap tubing, electrical tape, or another
suitable product to seal all cable connections appropriately to prevent
moisture and corrosion damage from weather exposure.
•
Connectors should be tightened as shown below in the absence of
manufacturer advice specific to your cable:
o
Tighten Type N connectors to a torque of 0.68 to 1.13 N-m (6 to
10 inch-lbs).
o
Tighten Type TNC connectors to a torque of 0.45 to 0.68 N-m (4
to 6 inch-lbs).
•
Use only specified cables for the Iridium network as supplied by Beam or
refer to the specification table below.
