No structure or equipment of any kind shall be attached to the finished exterior surface of the roof, walls or other portions of any building containing townhouses and/or flats other than residential-style lighting fixtures, gutters, downspouts, shutters, structures, fixtures or equipment required for compliance with the Uniform Construction Code and/or a maximum of one satellite dish antenna per unit, not exceeding one meter in diameter, and located wholly within the perimeter of a deck, balcony or patio attached to and intended for the exclusive use of residents of the unit served by the satellite dish antenna. Such deck, balcony or patio must be surrounded by a railing not exceeding 36 inches in height or the minimum height required by the Uniform Construction Code, whichever is greater. No portion of the satellite dish antenna may extend above the top of the surrounding railing, unless the unit owner shall establish that, in the particular case of the unit in question, this requirement will unreasonably impair signal reception. Any satellite dish antenna herein permitted and all of its appurtenances must be painted to match, or blend with, the predominant color of the background surrounding the antenna, as determined by the reviewing authority issuing approvals for installation of the antenna.
