16. Carts and Stands
The equipment should be used only with a cart or stand
of sufficient strength and stability for the use intended.
16A.
An equipment and cart combination should be moved
with care. Quick stops, excessive force, and uneven
surfaces may cause the equipment and cart combination

lines.
18.
Outdoor Antenna Grounding
If an outside antenna is to be used with the
HafIer
Tuner,
be sure that the antenna system is grounded so as to
provide some protection against voltage surges and built
up static charges. Section 8
10
of the National
Electrical
Code,
ANSl/NFPA
No.
70-
1984,
provides information
with respect to the 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, connections to
grounding electrodes, and requirements for the ground-
ing electrode. See Figure 1.
