H. Comparator shall be capable of storing basic statistical data such as count and duration that aparticular receiver was selected; number of receiver or line failures, etc. Such data shall beavailable on a port using a PC.I. Comparator shall be capable of applying a user-defined weighting value or prioritizationfunction to prefer certain receivers above others.J. Comparators shall be equipped for DC battery float operation unless specified otherwise.Tower Top PreamplifiersTower-top preamplifiers/filters will not be used.Antenna SystemsAntennasThe selection and design of antennas, transmitter combiners, and receiver multicouplers will bethe responsibility of the contractor, but shall comply with the following specifications:A. Each antenna shall be equipped with a dedicated transmission line to the combiner ormulticoupler equipment.B. All antennas shall be mounted to minimize the pattern distortion effects caused by towermembers, transmission lines, other antennas, and other objects located near the antenna.C. Receive antennas shall be plumbed and mounted vertically above the transmit antennas asspace on the towers permits.D. Antennas shall meet or exceed the requirements of Part I of EIA-329-A. Separate transmitand receive antennas shall be provided unless otherwise specified.E. Multiple-feed antennas for transmitters (having separate elements inside one antenna radome)may be used to minimize tower loading and allow more space for other antennas.F. Antennas shall be high quality, ruggedized models, designed for long-term, high-reliabilityperformance under high wind conditions, and for minimal generation of passiveintermodulation.G. Repeater sites shall use Decibel Products DB-408, DB-420 or approved equivalent antennas.Transmission LinesA. Andrew LDF5-50A, 7/8 inch Heliax® cable shall be used for the major portions of the cableruns. Outdoor cable runs shall be continuous lengths, unless cable lengths exceed themaximum length supplied by the manufacturer. The manufacturers’ minimum bending radiusshall not be exceeded during installation.B. Andrew FSJ4-50B, 1/2 inch super-flex Heliax® cable shall be used in short lengths wheregreater flexibility is necessary. This includes each antenna and connection to all equipment.C. All cables shall be terminated in N-type connectors unless equipment requires otherwise.Connectors shall be constructed of non-ferrous materials, and shall have gold plated innerconductors and silver-plated bodies. Andrew Model LDF5-P, premium performance, Type Nmale and female connectors shall be used for all transmission line connections.City of San Luis Obispo 20 Radio System Upgrade TECHNICAL APPENDIX
D. Easiax cable cutting tool, Andrews Model 222951, shall be used to terminate all cables. Forreplacement blades, use Andrews Model 222954 blade kit (5 per kit).E. Antenna connectors shall be weatherproofed, using Andrew type 221213 weatherproofing kitor approved equivalent. Butyl-rubber tape shall be applied liberally to the antenna connectorand 3M Scotchcoat® shall be applied liberally over the butyl-rubber tape.F. Cable selection shall minimize transmission losses to less than 10% of total transmitterpower; this shall include connector losses.G. Transmission lines shall be secured through standard cable hangers attached to channelsupports or "Unistrut" as appropriate. All cables shall be dressed appropriately, and runparallel to each other.H. Antenna transmission lines shall be grounded just prior to entering the facility.I. When required, six-opening feed-through panels shall be provided at repeater sites, if theexisting is filled to capacity. Feed-throughs shall be similar to Andrew model 48940-6. Wallfeed-through boots shall be sized for the correct cable OD. Feed-through panels, boots andunused ports shall be sealed to prevent moisture and dust intrusion.J. Each transmission line shall be protected from lightning and static discharges with anappropriate Transient Voltage Surge Suppression (“TVSS”) device designed with a voltagehandlingcapability to support the number of transmitters anticipated, plus one future. TheTVSS device shall conform to all of the requirements shown elsewhere in this Specification.These devices shall be connected to the facility grounding system as described elsewhere inthis specification.K. TVSS units shall be mounted to contractor-provided copper cage assemblies that shall beinstalled at transmission line entry ports. This cage shall both ground and support TVSSunits. TVSS units shall be mounted in the cage in such a fashion as to permit easydisconnection of cables to/from external antennas for testing.Antenna Support StructuresDetails of antenna mounting shall be determined by the contractor, as required by the availabilityof support structures at each site and the contractor's specific design, and in coordination with theCity’s Project Manager.All contractor-provided hardware shall be the highest-quality stainless steel or galvanized.Antenna brackets shall be Andrews/Decibel Products models or engineer-approved equal.Cable Support StructuresThe City shall provide all indoor and outdoor cable support structures unless otherwise noted.This includes cable trays, ladders and “Unistrut” where application. However, contractor isrequired to provide cable support and standoff brackets, etc., as applicable, which will mount toCity-provided supports. All contractor-provided hardware shall be the highest- quality stainlesssteel or galvanized. Hardware shall be Andrews/Decibel Products models or engineer-approvedequal.Fire Station 1 Tower Antenna SystemA. The contractor shall supply and install all antennas, mounting brackets and hardware,transmission lines, connectors, TVSS devices and other hardware on the new FS#1City of San Luis Obispo 21 Radio System Upgrade TECHNICAL APPENDIX
