iDirect Evolution X1 Outdoor Satellite Router Installation and Safety Manual 57
Appendix C Preparing the
Coax Cable
Note: The procedures in this section, for preparing outdoor coaxial cables, are meant
to be generic in nature. Although specific brands of tools and parts are used in
this section, cables and connectors should be installed per manufacturer’s
requirements specific to the brands preferred. In general, specific and detailed
instructions are for RG-6 cables and connectors, only.
Use high quality coaxial outdoor cable to connect the iDirect Evolution X1 Outdoor Satellite
Router to the Outdoor Unit (ODU) equipment. iDirect recommends that a solid copper center
conductor, coaxial cable be used with a minimum of 60% + 40% braid and double foil shield to
connect the equipment, such as:
• RG-6 — 0.04 inch (1 mm), outdoor rated, Quad Shielded, solid bare copper center
conductor, for cable lengths less than or equal to 225 feet (68.5 meters)
• RG-11 — 0.064 inch (1.6 mm), outdoor rated, Quad Shielded, solid bare copper center
conductor, for cable lengths less than or equal to 400 feet (121.9 meters)
Before connecting the cables, connectors on each end must be installed.
The center conductor must be straight and extend 1/8 inch (3.2 mm) beyond the end of the F-
connector, and the connector should be securely crimped to the cable.
Note: iDirect does not recommend using RG-59 with solid bare copper center
conductor. RG-6 or RG-11 Quad Shield or other outdoor quality, 75-ohm type of
coax can be used.
If different types of coaxial cable are used other than the recommended quad shield RG-6,
the following problems can occur:
• 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.
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.
