iQ LTE Satellite Router
Coax Cable Preparation
• Co-channel interference causes degradation and higher packet loss rate
• Good return loss – High quality cable and correct connectors help ensure an optimal
return loss of 10 dB or more
To terminate the cables with F-Type connectors:
1. Cut off each end of the coax cable squarely, using the proper cable cutter as shown in
Figure C-1 .
Figure C-1. Coax Cable Cutting Technique
2. Remove the jacket material and foam insulation according to the length defined under
Length A in Table C-1 . For RG-6, use a two-step Coax Stripper such as the LC-CST 1257
from Paladin Tools.
NOTE: Excessive DC Resistance – will result in excessive voltage drop across the
IFL cable. Hence, the voltage at the BUC may be too low to operate properly.
NOTE: Appendix B, Tools Needed on page 37 lists all of the recommended tools
for terminating coax cables.
WARNING: Wear protective eye wear while cutting cables and terminating
connectors.
WARNING: The center conductor must be straight and cylindrical without any
burrs. Failure to do so can damage the satellite router, BUC, and/or LNB input
connector.
