Coax Cable Preparation
• Co-channel Interference – If signals at the same frequency are carried on long, parallel
runs of coaxial cable (for example, in cable trays, or riser) interference can occur
between the signals
• Higher quality cable helps to prevent this with better shielding
• 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 B-1 .
Figure B-1. Coax Cable Cutting Technique
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 A, Tools Needed on page 23 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.
