Orange County NC <br /> 30 <br /> Radio Communication Tower and System Infrastructure Upgrade <br /> RF Coverage and Sites/Towers <br /> 2.2.4 Chatham Mountain Site <br /> Currently the Fire Station paging station and antenna are at the 1000 ft. level on the <br /> Chatham Mountain tower. At this height the FCC license limits RF power output and <br /> effective radiated power. As discussed with Orange County, a height of 150 ft. would be <br /> more appropriate for obtaining paging coverage in the southern part of the County. Also, <br /> the use of a directional antenna will enhance coverage into Orange County. <br /> Also, a site at StarPoint Storage was reviewed, to be used in lieu of the Chatham site. <br /> This site provides better RF coverage into the southeast corner of Orange County, <br /> however, RF coverage into the southwest corner is decreased. FE prepared RF <br /> Coverage maps for the StarPoint Storage site as well, which can be found in Section <br /> 2.2.5. <br /> Following discussion with Orange County, FE reviewed and analyzed the Chatham site <br /> further, to determine if adjusting the antenna height and antenna orientation would <br /> result in improved VHF RF coverage into the southeast and southwest corners of the <br /> County. <br /> By raising the antenna height to 200 ft., FE found that RF coverage could be improved <br /> in the southeast corner of the County, while not significantly reducing coverage in the <br /> southwest corner. Figure 16 shows the predicted VHF RF coverage using an antenna <br /> height of 200 ft. at the Chatham Mountain site. <br /> 2.2.5 VHF Paging Coverage <br /> VHF paging coverage has been predicted and plotted, as shown in Figure 14 through <br /> 16 below. <br /> August 30, 2013 Page 29 of 51 ° <br />
