Anchor guys will be effectively grounded and will be electrically continuous to earth through the anchor. Therefore, these guys shall not be broken with strain insulators. A guy bond clamp will be inserted in all bolt and nut thimbleeyes, except at pole-to-pole guys, where ground continuity is not dependent upon the pole-to-pole guy.
(b) 
If the strand at dead ends is not effectively earth-grounded, it will be so grounded by a length of No. six solid bare copper wire bonded to the messenger with compression ground clamps and the copper wire bonded to a ground rod driven its full length (and six inches below the surface) into the earth.
(c) 
All equipment cabinets, cans, fused cutout cabinets, metal meter socket bases, etc., will be grounded through a length of No. six solid bare copper wire bonded to a minimum eight foot ground rod driven to its full length (and six inches below the surface) into the earth.
(Ord. 1422 § 18, 1968)
(a) 
Strand. On joint use poles, the CATV system strand will always be attached to the side of the pole to which the telephone strand has been attached.
(b) 
Equipment installed in shielded, rain-tight, ventilated metal cabinets will be mounted on a crossarm so that there is a free climbing space of fifteen inches from the center of the pole to the ends of the cabinet. Crossarms will be mounted parallel to the strand.
(c) 
Power Supply Facilities. All attachments to power utility secondaries, which are made to power television transmission system equipment, will conform to the standards and specifications governing such attachments which are defined in the joint use agreement with the respective utility. Where such attachment practices are not specified in the joint use attachment agreement, such power attachments will satisfy the following minimal requirements:
(1) 
A two-wire No. twelve weatherproof entrance cab will be used from the service head to the fused cutout cabinet and from the cutout cabinet to the pole-mounted equipment enclosure;
(2) 
The neutral side of the power drop will be continuous and unfused;

A single entry cable will be installed for each building with suitable distribution devices which will divide the signal for distribution to multiple receivers if such multiple connections are required.
(b) 
The CATV system attachment to a building will have a clearance from power and telephone attachments of at least twelve inches. The same clearance will apply along the length of the building run when the CATV system cable parallels power and telephone service wires.
(c) 
The CATV system service drop will not enter the building through the entrance hole or tube used for entrance of telephone or power service wires.
(d) 
Cable will enter the building through a hole that has been suitably covered and weatherproofed. Cable will run from the point of entrance to the terminal outlet without the need for conduit. Suitable clamps or staples for the attachment of the coaxial cable to floor joints or wall studs will be used.
(e) 
Receiver isolation or tapoff units will be installed utilizing the shortest possible distance between building and feeder distribution line. A spacing of not less than four feet will be kept between such receiver isolation units. These units will provide means to secure the bonding of messenger strand, drop support wire and outer conductors of feeder as well as of house drop cable.
(f) 
All house drops will be supported by suitable strand or messenger wire (109 steel line wire or suitable equivalent and lashed with forty-five thousandths inch stainless steel lashing wire). Fire "8" integral messenger RG-59U is acceptable under this provision.
(g) 
Grounding devices will be employed to ground the outer conductor of the subscriber's drop coaxial cable in such manner as to insure that the outer conductor of this cable is at ground potential throughout its entire length. Both the shield and center conductor will isolate DC to low frequency AC from the input terminals of the receivers connected to the system by blocking capacitors or transformers.
(Ord. 1422 § 20, 1968)
All underground installation of cable or equipment, or both, shall be of the highest standard adopted by and approved for use by telephone companies for similar cable and equipment devoted to the same or similar use and taking into account the place of installation, the quality and quantity of the load upon such cable or equipment and similar factors.
