Outdoor Antenna Grounding
If an outside antenna
or cable system is
connected to the FS-
100, verify that the
antenna or cable
system is grounded.
This provides some
protection against
voltage surges and
built-up static charges.
Refer to Article 810 of
or cable system is
connected to the FS-
100, verify that the
antenna or cable
system is grounded.
This provides some
protection against
voltage surges and
built-up static charges.
Refer to Article 810 of
the National Electric Code, ANSI/NFPA 70, for information about
the proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of
grounding connectors, location of antenna discharge unit,
connection to grounding electrodes, and requirements for the
grounding electrode.

Ground Loop WARNING:
To avoid earth or ground loops, insure that all equipment
connected to the FS-100 share a common ground. Use a single,
grounded outlet strip as opposed to separate outlets with the
possibility of different ground potentials.

Lightning and Power Surges
During electrical storms or when left unattended and unused for
long periods of time, unplug the FS-100 from the power source
and disconnect the antenna or cable system.

Power Lines
Do not locate an outside antenna system in the vicinity of
overhead power lines, electric light or power circuits, or where it
can fall onto such lines or circuits.
When installing an outside antenna system, extreme care should
be taken to keep from touching such power lines or circuits as
contact with them might be fatal.
