A. Building Permit Required

of the building official where required by the Building Code.

B. Development Standards
All disc antennas shall be located, designed, constructed,
treated, and maintained in accordance with the following
standards:
(1) Antennas shall be installed and maintained in compliance
with the requirements of the Building Code.
(2) Disc antennas exceeding thirty-six (36) inches in
diameter shall not be permitted on the roof, except
where there is no other location on the lot which
provides access to receiving or transmitting signals.
In no case shall any part of any antenna be located more
than 10 feet above the apex of the roof surface.
Antennas mounted on the roof shall be located in the
least visible location as viewed from adjacent public
rights-of-ways, and residential structures in
residential zones.
(3) No more than one disc antenna shall be permitted on each
tract of land.
(4) Ground mounted disc antennas shall be erected or
maintained to the rear of the main building, except in
those instances when the subject property is cul-de-sac
or corner lot where the side yard is larger than the
rear yard, in which case the antenna may be located in
the side yard. Antennas shall not be located in any
required setback area. No portion of an antenna array
shall extend beyond the property lines or into any front
yard area. Guy wires shall not be anchored within any
front yard area but may be attached to the building.
(5) Antennas may be ground-mounted, free standing, or
supported by guy wires, buildings, or other structures
in compliance with the manufacturer's structural
specifications. Ground-mounted antennas shall be any
antenna with its base mounted directly in the ground,
even if such antenna is supported or attached to the
wall of a building.
(6) The antenna, 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. Antennas shall be
screened through the addition of architectural features
and/or landscaping that harmonize with the elements and
characteristics of the property. The materials used in
constructing the antenna shall not be unnecessarily
bright, shiny, garish, or reflective. Whenever
possible, disc antennas shall be constructed out of mesh
material and painted a color that will blend with the
background.

(7) Antennas shall meet all manufacturer's specifications.
The mast or tower shall be non-combustible. Corrosive
hardware, such as brackets, turnbuckles, clips, and
similar type equipment if used, shall be protected by
plating or otherwise to guard against corrosion.
(8) Every antenna must be adequately grounded, for
protection against a direct strike of lightning, with an
adequate ground wire. Ground wires 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 inches
from combustible materials. Lightning arrestors shall
be used that 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. When lead-in
conductors of polyethylene ribbon-type are used,
lightning arrestors must be installed in each conductor.
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.
(9) Antennas may contain no sign or graphic design as
defined in the Ashland Sign Code, even if the sign is
permitted on the property."
