VHF Mobile Radio Technical SpecificationsTable 17A. – VHF Mobile Radio Transmitter Technical Specification - FireFrequency range150 -174 MHzFrequency spread (min.), no degradation24 MHzProgrammable channel steps2.5 and 7.5 kHzPower output, vehicular (EIA Intermittent)50 WSpurious and harmonic emissions-70 dBcTable 17B. – VHF Mobile Radio Receiver Technical Specification - FireFrequency range150-174 MHzFrequency spread (min.), no degradation24 MHzChannel steps2.5 and 7.5 kHzAnalog Sensitivity, 12 dB SINAD-116 dBmDigital Sensitivity, 5% BER (DAQ 3.0)-116 dBmSelectivity, EIA, @ 25 kHz bandwidth (analog) -80 dB@ 12.5 kHz bandwidth (analog) -70 dBIntermodulation immunity-80 dBSpurious and image rejection-80 dBSpeaker input power, (minimum)8 WEquipment Housing and Physical RequirementsA. The transceiver housing shall house all electronic circuits and/or circuit cards associated withthe equipment.B. Microphones, external speaker housings and transceivers housings shall be constructed ofhigh impact polycarbonate plastic or other suitable high impact material.C. Trunk mounted transceiver housings shall be equipped with a base plate. The base plate shallallow for the removal of the transceiver from its mounted location for replacement orservicing. Removal of the transceiver from the base plate shall not expose its internalcircuitry.D. The physical operating requirements for mobile radios are:1. The radio and associated hardware shall meet specifications under ambient conditions of-30° to +60° C, and 5% to 90% relative humidity.2. The equipment shall meet or exceed all the requirements of MIL-STD 810C, D and Estandards for shock, vibration, salt, fog, dust and rain.3. Cable connectors shall be securely attached to the mobile via hermetically sealedconnectors.4. Fuses or circuit breakers installed in vehicles shall be easy to reach, labeled "RADIO",and have the proper replacement fuse amperage identified.5. One spare fuse for each mobile installation shall be provided.6. Details of mounting and installation will vary among vehicle types and shall becoordinated with the fire mechanic.City of San Luis Obispo 56 Radio System Upgrade TECHNICAL APPENDIX
Vehicle AntennasA. All vehicular antenna cable kits shall be tested with an antenna, or a matched load. Cable kitsexceeding a 1.5:1 VSWR shall be replaced with NMO-style mounts.B. All existing quarter-wave UHF vehicular antennas shall be replaced with new AntennaSpecialists ASPR7495 wideband quarter-wave units. Motorola or Antenna Specialists UHFmodels with 5 dB gain shall be retained if in good condition. Assume 25% of vehicles have 5dB gain antennas.C. All existing VHF fire antennas shall be replaced. Single band antennas shall be AntennaSpecialists ASP7455 3 dB gain units. Proposers shall recommend a Dual-band (460/155MHz) model.D. All antennas and cables shall be tested to confirm that the VSWR is less than 1.5:1.E. The roofs of some City vehicles are fiberglass, and antenna installation may require theaddition of a ground plane, to be supplied and installed by the contractor. Contractors are towork with the City to determine which units require such ground planes.City of San Luis Obispo 57 Radio System Upgrade TECHNICAL APPENDIX
