2.1.3 RF Cable Installation Guidelines
• For all coaxial connections to/from the Repeater – use high performance, low-loss,
50 ohm coaxial communication cables.
• All cables shall be weather-resistant type.
• Cable length – determined by the Repeater installation plan. When calculating the
cable length, take into account excess cable slack so as not to limit the insertion
paths.
• Make sure the cable and the connector are compatible. Using cables and connectors
from the same manufacturer is helpful.
• All connectors must be clean and dry.
• Waterproof all outdoor connections using silicon, vulcanizable tape or any other
suitable substance, as moisture and dust can impair RF characteristics
• Make sure enough room has been allocated for the bending radius of the cable. RF
cables must not be kinked, cut or damaged in any way.
• Connect the RF cable to the antenna tightly but without damaging threads.
• Fasten cable tightly to cable ladder or aluminium sheet.
• For short length feeder cables, use 1/2”; for longer feeder cables, use 7/8”. Choose
thicker coax cables for lower attenuation. Minimize the length of the coax cables to
reduce attenuation.
• Use jumper cable for easy installation. The RF coaxial cable can be substituted at
each end with a jumper cable.
2.1.4 F/O Cable Installation Guidelines
Use the following over the complete link between the Remote and OMU:
• Use angled APC connectors at 8deg angle.
• APC type ODF connections.
• Cable length - determined by the Remote installation plan. When calculating the
cable length, take into account excess cable slack so as not to limit the insertion
paths.
Recommended Fiber-optic cable:
