p 13 3. Single braid coax cable is prohibited. Double shielded cable must have over 98.5% shield coverage. Single braid cable with resistive terminations is acceptable ONLY as a fixed method for relative signal strength measurements. 4. Jacketed coaxial cable is required, unjacketed transmission line of any type is prohibited. 5. Use of N, TNC, DIN or other types of constant impedance connector is preferred over a non- constant impedance type. Every effort should be made to prevent the use of coax adapters. 6. All equipment is to be grounded. Grounding is to be done with low impedance conductor to the station ground grid, preferably with flat copper strap or heavy braid. The "green wire" of the AC power plug is not an acceptable grounding point. The site manager has the responsibility of providing a suitable ground for users. 7. Transmitting systems must be checked periodically, which includes the isolator, VSWR on the load port of the isolator, and overall system insertion loss. 8. Bare metallic ties are prohibited for securing transmission lines to towers. In the case of large lines, use of stainless steel or galvanized hangers is permitted. Hardware capable of rusting and dissimilar metals is prohibited. Transmission lines are to be insulated from metallic structures/objects. It is the duty of the installation personnel to prevent "diode junctions" from taking place. 9. All loose wire or metal objects are to be removed from the tower and site. Metal fencing should be plastic coated. 10. All equipment shall be licensed and operated in full accordance with all applicable rules and regulations of the regulating agency, (FCC, NTIA). There shall be no modifications that violate "FCC Type Acceptance." 11. It is recommended that all equipment be labeled with the owner's name and a current 24- hour telephone contact number, (service agency is acceptable). 12. Every effort should be made to protect the equipment from lightening damage. Feed- through lightning protectors should be used on all coaxial cable connections to equipment enclosures. Gas, Gap, MOV and Silicone Avalanche Diode (SAD) protectors should be used in control, audio, telephone, and power connections. INTERFERENCE POLICY STATEMENT In the event Radio Interference (RI) occurs, all users of the site are required to participate in solving the problem by providing technical personnel and test equipment to locate the source of the specific problem. If these standards are complied with, additional isolators, filters, cavities, etc., may be required. All equipment must be maintained in good working order and meet original manufacturer's and FCC specifications for reduction of transmitter spurious radiation. In the event radio interference (RI) occurs, and these standards are complied with, additional isolators, filters, cavities, etc. may be required to correct specific problems. Involved systems, not in full compliance with these standards, will be asked to comply immediately at their own expense. It is customary for the offending transmitter owner/operator to finance the required corrections of equipment necessary to correct the problem. It is also good practice to allow the affected 196 Page 25 of 30
