Grounding the IF Cable

Grounding points of the IF cable
The grounding point depends on the installation mode and the length of the IF cable. Generally, the IF cable
should be grounded to a minimum of three points. When the IF cable is longer than 60 meters (196.85 ft), add a
grounding point for every extra 30 meters(98.42 ft).
As recommended in ITU K.56, the IF cable does not need to be separately grounded under the ODU,if the
ODU is properly grounded. The IF cable is grounded through the ODU.
