Step 8. Failure to use the lower loss cable for extended lengths will result in significant
reduction in ODU output power and excessive signal distortion.

General Cable Installation Considerations
General guidelines to ensure that the IDU to ODU Coaxial Cables are properly
prepared and installed are listed below:
1) Plan the route that the IFL cables will follow. Plan the route to minimize the
cable length between the IDU and ODU. Keep in mind that approximately five
feet at both ends should be added for drip loops and service loops.
2) Ensure that a strain relief is added to both cable connections.
3) Ensure that the external connector is sealed and waterproofed.
4) When running the cable between the IDU and ODU, follow standard installation
practices. Avoid sharp corners. Secure the cable to the tower members, cable
runways or other using hangers or manufacturer’s approved tie-wraps at one
meter (three-foot) intervals.
5) Ensure that the center pin of the type “N” male connector does not protrude
beyond the inner metal ground shield. An improper terminated cable will
damage the mating connectors of the IDU and ODU.
