Product Description

Iridium Custom Cable Kit

Iridium Customized Cable Kit SKN6121B.  Replaces SKN6121A

Includes:

  • .5 meter flexible outdoor jumper cable (TNC-Male/N-Male)
  • 1.5 meter flexible indoor jumper cable (N-Male/TNC-Male)
  • Lightening surge protector

Cable Selection:

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 1.5dB.

Together, these cables yield an end-to-end solution that meets the "3 dB" requirement. Alternatively, the user can purchase custom cable lengths from other suitable sources. Two suggested sources are Times Microwave (www.timesmicrowave.com) and Andrew Corporation (www.andrew.com). Tables 1 and 2 list a selection of coaxial cables that meet the 3 dB requirement when used with the Custom Cable Kit.
