[Ord. No. 726, 11-14-1989]
No person shall erect or install an outside television mast,
tower or antenna in the jurisdiction of the City without having first
obtained a permit therefor from the office of the City Building Official.
[Ord. No. 726, 11-14-1989]
(1)
An Underwriters' Laboratories approved lightning arrestor or
its equivalent is required on all antenna lead-ins under this division
unless the lead-in is of the metal shield type with the metal shield
properly grounded.
(2)
Lead-in conductors attached to buildings shall be so installed that
they cannot swing within two feet of conductors carrying 250 volts
or less, or within 10 feet of conductors carrying more than 250 volts.
The clearance between lead-in conductors and any conductor forming
part of a lightning rod system shall not be less than six feet. That
part of the lead-in that comes in contact with the building shall
be supported at intervals of not more than 15 feet apart.
(3)
Conductive supporting poles, masts or other structures supporting
antennae shall be permanently and effectively grounded with a minimum
of No. 10 copper or No. 8 aluminum wire. Poles or masts which are
themselves the sole antenna are exempt from this rule.
(4)
No television mast, pole, tower or antenna shall be mounted or attached
to a chimney.
(5)
Poles or masts over 12 feet in height must be guyed with three or
more wires to one position. Masts or poles 20 feet to 30 feet must
be guyed to a minimum of two positions with the uppermost guy wires
to be within two feet of the top of the antenna. The angle of the
guys must not be less than 30° from the vertical mast, and the
wire used shall be of the stranded rust-proof type. Anchors shall
be of equal strength or stronger than the combined wires connected
to them. All guys fastened to the ground shall be protected by a sufficient
safety guard to a minimum of eight feet vertically from the ground.
(6)
All self-supporting towers, poles or masts shall be designed and
installed to withstand an actual wind velocity of 90 miles per hour.
(7)
Metal supporting poles, masts, towers or other structures located
on buildings provided with lightning protection must have an interconnection
between the grounding conductors and the lightning surge conductors.
(8)
Plumbing vent stacks or natural gas piping shall not be used to ground
antenna masts, poles or towers; instead, all grounding conductors
shall be attached preferably to a cold water pipe supplied by an underground
water distribution system, with the water meter properly jumped. Where
not available, grounding conductors shall be attached to a standard
driven copper-weld ground rod six feet long or longer. No pole, mast,
tower or structure used to support antennae shall be so located that
in falling it might fall across a utility distribution line of over
250 volts. The separation distance between the television antenna
support and the utilities distribution pole line carrying an access
of 250 volts measuring along the ground line must be the height of
the antenna plus five feet.
(9)
All towers, masts, poles or antennae attached to a building shall
be noncombustible and corrosive-resistant.
[Ord. No. 726, 11-14-1989]
It shall be unlawful for any person to sell, install or operate,
within the corporate limits of the City, any appliance, device, apparatus
or equipment, the use or operation of which will cause or does cause
high frequency or other oscillations that interfere with radio or
television broadcast reception within the corporate limits of the
City.
