Orange County NC 29 <br /> Radio Communication Tower and System Infrastructure Upgrade <br /> RF Coverage and Sites/Towers <br /> 2.2 VHF Station Paging <br /> 2.2.1 Cedar Grove Fire Station <br /> An existing tower at this location could be used for a VHF paging station. <br /> The tower is approximately 175 ft. tall, and has two antennas and transmission lines <br /> installed. The latest information from Orange County indicates that neither of these <br /> antennas or transmission lines is in use. <br /> If an existing antenna and transmission line is used for the new VHF paging station, a <br /> structural analysis of the tower should not be necessary. However, depending on the <br /> age of the tower, a tower inspection and structural analysis would be recommended. <br /> If an existing antenna and transmission line is used for the new VHF paging station, the <br /> antenna and transmission line should be tested for acceptable performance. The <br /> antenna and line should be "swept" with a time domain reflectometer (TDR). This will <br /> provide an indication of acceptable performance as well as provide a baseline for future <br /> testing and verification. <br /> 2.2.2 Orange Grove Fire Station <br /> A new tower is proposed for the Orange Grove Fire Station to provide VHF paging <br /> coverage in the central southwest of the County. <br /> Based on the RF coverage requirements, a tower height of at least 130 ft. is needed for <br /> Fire Station paging. To allow for future expansion and other use of the tower, Orange <br /> County may consider a tower of greater height. <br /> Initial review of the Unified Development Ordinance indicates that to meet a 110% fall- <br /> zone for the tower, the new tower would be limited to 100 ft. If Orange County could <br /> secure approvals from the adjacent land owners, this fall-zone may be extended onto <br /> their properties, and the tower height increased. <br /> A full tower elevation and UDO Report is attached as a separate document. <br /> 2.2.3 Eno Mountain Site <br /> The existing Fire Station paging station at this site should be continued to be used as <br /> part of the overall County VHF paging system. <br /> August 30, 2013 Page 28 of 51 � a <br /> e -. <br />
