Outdoor antenna grounding
If an outside antenna or cable system is connected to your DVD
combo, make sure that the antenna or cable system is grounded to
provide some protection against voltage surges and built-up static
charges. Article 810 of the National Electrical Code, ANSI/NFPA No.
70, provides information with respect to correct grounding of the mast
and supporting structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, location of the
antenna-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
Note to CATV system installer
This reminder is provided to call the CATV system installer’s attention
to Article 820-40 of the NEC that provides guidelines for correct
grounding and in particular, specifies that the cable ground must be
connected to the grounding system of the building as close to the
point of cable entry as practical.
Lightning
For added protection for your DVD combo’s receiver during a lightning
storm, or when it is left unattended and unused for long periods of
time, unplug it from the power outlet and disconnect the antenna or
cable system. This helps prevent damage to your DVD combo from
lightning and power line surges.
