Important Safety Instructions
18. Use proper power sources – Plug the product into
a proper power source, as described in the operating
instructions or as marked on the product.
19. Avoid power lines – Use extreme care when
installing an outside antenna system to keep from
touching power lines or circuits, as contact with
them may be fatal. Do not install external antennas
near overhead power lines or other electric light or
power circuits, nor where an antenna can fall into
such circuits or power lines.
20. Ground all outdoor antennas – If an external
antenna or cable system is connected to this
product, be sure the antenna or cable system is
grounded. This will provide some protection against
voltage surges and built-up static charges.
Section 810 of the National Electrical Code ANSI/
NFPA No. 70 provides information with respect to
proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection to
grounding electrodes, and requirements for the
ground electrode. Refer to the antenna grounding
illustration on this page.
