Single braid coax cable is prohibited. Double shielded cable must have over 98.5% <br /> shield coverage. Single braid cable with resistive terminations is acceptable ONLY as <br /> a fixed method for relative signal strength measurements. <br /> Jacketed coaxial cable is required. Unjacketed transmission line of any type is <br /> prohibited. <br /> Use of N, TNC, DIN or other types of constant impedance connector is preferred over <br /> a non-constant impedance type. Effort should be made to prevent the use of coax <br /> adaptors. <br /> All equipment is to be grounded. Grounding is to be done with low impedance <br /> conductor to the station ground grid, preferably with flat copper strap or heavy <br /> braid. The "green wire" of the AC power plug is not an acceptable grounding point. <br /> The site manager has the responsibility of providing a suitable ground for users. <br /> Transmitting systems must be checked periodically, which includes the isolator, <br /> VSWR on the load port of the isolator and overall system insertion loss. <br /> Bare metallic ties are prohibited for securing transmission lines to towers. In the <br /> case of large lines, use of stainless steel or galvanized hangers is permitted. <br /> Hardware capable of rusting and dissimilar metals are prohibited. <br /> Transmission lines are to be insulated from metallic structures/objects. It is the duty <br /> of installation personnel to prevent "diode junctions" from taking place. <br /> All loose wire or metal objects are to be removed from the tower and site. Metal <br /> fencing should be plastic coated. <br /> All equipment shall be licensed and operated in full accordance with all applicable <br /> rules and regulations of the regulating agency, (FCC, NTIA). There shall be no <br /> modifications which violate "FCC Type Acceptance." <br /> It is recommended that all equipment be labeled with the owner's name and a <br /> current 24- hour telephone contact number, (service agency is acceptable). <br /> Every effort should be made to protect the equipment from lightning damage. Feed- <br /> through lightning protectors should be used on all coaxial cable connections to <br /> equipment enclosures. Gas, Gap, MOV and Silicone Avalanche Diode (SAD) <br /> protectors should be used in control, audio, telephone and power connections. <br /> cw-t4.19.24 <br />
