MINIMUM SITE STANDARDS New Water Tower Communications Site City of Ramsey, Minnesota All equipment must be housed in an RF tight, metal enclosure that provides at least 60 db of attenuation to any internal RF signals. Desk-top base stations and open racks cannot be used; additional shielding kits may be required. Front and rear access to the equipment cabinets is available. Three feet front and rear access space is provided for all equipment spaces. At least 60 db of isolation for 450 MHz and 800 MHz transmitters and 25 db of isolation for 150 MHz and 40 MHz transmitters must be provided; a band pass cavity must be provided on the transmitters between the antenna and any ferrite device used/ Additional filtering and isolation may be required and will be considered on a case-by-case basis. Maximum transmitter power allowed into the antenna feed line will be 110 watts per transmitter. (Higher power levels will be considered on a case-by-case basis; additional protective devices wilt be required.) Only jacketed copper Heliax cable will be permitted for transmission line at the site. Ail on-site intercabling must use RG/9, RG/142, RG214 or 1/2 inch Superflex. RG/8 or any other single shielded cable will not be allowed. Exposed exterior coaxial cable must be painted "eggshell" white. Proposed transmitters that will cause second order or third order intermodulation products on existing receiver frequencies will not be permitted on the site. A receiver with the same frequency as an existing second order or third order intermodulation product at the site, will not be permitted on the site. Three signal intermodulation interference will be evaluated on a case-by-case investigation. All transmitters must have band-pass cavities that will provide at least the following attenuation of side band noise: 40 MHz band: 150 MHz band: 450 MHz band: 800 MHz band: 15 dB at 1 MHz 15 dB at 1.5 MHz 15 dB at 2.5 MHz 20 dB at 10 MHz Each cabinet must be identified by the owner's name, address and FCC station license; it also must have the name and telephone number of the responsible service agency. Prior to approving any application for antenna space at the site, an engineering study will be conducted for the City, consisting of at least the following items: I I I 1 I I I I I I I I I I I I I I
