Every antenna shall be located, designed, constructed, treated, and maintained in accordance with the following standards:
A. The antenna shall be installed and maintained in compliance with the requirements of the Building Code.
B. The maximum number of antennas that may be installed on any lot shall not exceed:
1. One ground-mounted antenna;
2. Two (2) roof-mounted antennas;
3. In the manufacturing and studio zones, more dish antennas may be permitted, according to Title 17 of this Code.
C. 1. In residential zones, roof-mounted antennas shall not extend higher than fifteen (15) feet above the maximum building height permitted in the zone, except a single vertical pole antenna may extend to twenty (20) feet above the peak of the roof; provided that a roof-mounted disc antenna shall not exceed twenty-four (24) inches in diameter.
2. In nonresidential zones, roof-mounted antennas shall not extend higher than fifteen (15) feet above the maximum building height permitted in the zone or fifteen (15) feet above the building upon which it is mounted, whichever is less.
D. 1. Ground-mounted antennas shall not exceed forty (40) feet in height, except remote communication installation facility antennas, as provided in the Zoning Code.
2. All satellite receiving and transmitting “dish” type antennas shall be installed in accordance with the provisions of the Zoning Code, as set forth in Title 17 of this Code.
E. Not more than one antenna shall be permitted on any lot when the boom or any active element of the antenna array is longer than fifteen (15) feet.
F. 1. Stacking of antennas may be permitted when stacked in a ground-mounted antenna configuration, provided that not more than three (3) such antennas are attached to the tower.
2. For the purpose of this Section, such antennas shall be considered one antenna and shall be subject to all the requirements of this Section.
G. Antennas shall be erected or maintained to the rear of the main building; provided that, when the subject property is a cul-de-sac or any lot with a side yard larger than the rear yard, the antenna may be located in the side yard.
1. Antenna towers or the supports therefor shall not be located in any street-facing setback area.
2. No portion of any antenna array shall extend beyond the property lines or into any front yard area.
3. Guy wires shall not be anchored within any front yard area, but may be attached to the building.
H. Antennas may be roof- or ground-mounted, freestanding or supported by guy wires, buildings or other structures in compliance with the manufacturer's structural specifications.
1. A ground-mounted antenna shall be an antenna with its base mounted directly in the ground, even if such antenna is supported or attached to the wall of a building.
2. A fixed-guy antenna tower shall be fascia-mounted or guyed according to approved standards.
3. A wire antenna that is not self-supporting shall be supported by objects entirely within the lot lines of the property upon which the antenna is erected, but not within a front setback.
I. Antennas, including guy wires, supporting structures and accessory equipment, shall be located and designed so as to minimize the visual impact on surrounding properties and from public streets.
1. Antennas should be screened through the addition of architectural features and/or landscaping that harmonize with the elements and characteristics of the property.
2. The materials used in constructing the antennas shall not be unnecessarily bright, shiny, garish or reflective.
J. The antenna shall meet all manufacturer's specifications.
1. The mast or tower shall be of noncombustible and corrosive-resistant material.
2. The miscellaneous hardware, such as brackets, turnbuckles, clips and similar type equipment subject to rust or corrosion, shall be protected with a zinc or cadmium coating, by either a galvanizing or a sherardizing process after forming, to guard against corrosion and to protect the elements against electrolytic action due to the use of adjoining dissimilar metals.
K. 1. Whenever it is necessary to install an antenna near power lines, or where damage would be caused by its falling, a separate safety wire must be attached to the antenna mast or tower, and secured in a direction away from the hazard.
2. Antenna transmission lines must be kept at least twenty-four (24) inches clear of utility lines.
L. Every antenna shall be adequately grounded for protection against a direct strike of lightning, with an adequate ground wire.
1. The ground wire shall be of the type approved by the latest edition of the Electrical Code for grounding masts and lightning arrestors, and shall be installed in a mechanical manner with as few bends as possible, maintaining a clearance of at least two (2) inches from combustible materials.
2. Lightning arrestors shall be used, which are approved as safe by the Underwriters' Laboratories, Inc., and both sides of the line must be adequately protected with proper arrestors to remove static charges accumulated on the line.
3. When lead-in conductors of polyethylene ribbon-type are used, lightning arrestors must be installed in each conductor.
4. When coaxial cable or shielded twin lead is used for lead-in, suitable protection may be provided without lightning arrestors by grounding the exterior metal sheath.
M. Reasonable conditions of approval may be imposed to mitigate any negative impacts caused by installation of the antenna.
1. The cost of any such condition to the applicant shall be considered in light of the public benefit derived from the condition.
2. Other than the manufacturer's trade name and/or logo, no antenna or the support structure therefore shall be used for any commercial advertising purpose.
N. All antenna components shall be Underwriters' Laboratories, Inc., approved as acceptable to the Building Official.
O. Ground-mounted antennas shall have their related cables installed in conduit underground from base of antenna to wall of building.
1. Conduit may be rigid steel or PVC.
2. Roof-mounted antennas may have related cables installed in conduit (threaded rigid) or run exposed, provided related cables are of hard usage type and grouped together.
3. All antennas are subject to Articles 810 and 820 of the 1984 National Electric Code, in addition to Culver City ordinances.
