Orange County NC 10 <br /> Radio Communication Tower and System Infrastructure Upgrade <br /> RF Coverage and Sites/Towers <br /> Contact with the tower owner has been established through the Chapel Hill Police <br /> Department, and discussions with the tower owner have taken place. <br /> A physical inspection of the tower revealed that it was installed in 1968. Since the tower <br /> uses hollow tube steel legs, a structural analysis would need to include inspection of the <br /> inside of the tubular tower legs to check for the amount of corrosion. Also, it is FE's <br /> subcontractor's opinion that the tower would fail the most current TIA/EIA guidelines. <br /> Following discussion with Orange County, it was agreed that a structural analysis on <br /> this tower at this time was not to be performed. <br /> Alternate locations in the same area as the WCHL towers should be investigated. At the <br /> direction of Orange County, FE reviewed the possible alternate locations for a site in <br /> this area. A site approximately 1,000 ft. to the south of WCHL could possibly be <br /> pursued. This alternative site is described in Section 2.1.5. <br /> FE predicted 800 MHz RF coverage for this site, and is shown in Figures 3 through 8, <br /> which can be found in Section 2.1.7. <br /> 2.1.4.1 Site/TowerDetails <br /> Address: E Franklin Street, Chapel Hill, NC <br /> Coordinates: 35-56-15.9, 79-01-35.2, and 35-56-19.0, 79-01-36.1 <br /> Tower Type: guyed <br /> Tower Height: 200 ft. <br /> Proposed VIPER antenna heights: <br /> ® 1-800 MHz Tx antenna — DB809 (max 12.2 ft.), 170 ft. centerline <br /> ® 1-800 MHz Tx transmission line— 1 '/ inch <br /> • 1-800 MHz Rx antenna — DB809 (max 12.2 ft.), 187 ft. centerline <br /> • 1-800 MHz TTA— 16"H x 12"W x 7.5"D, 39#, 187 ft. or close to bottom of Rx <br /> antenna <br /> • 1-800 MHz Rx transmission line— 7/8 inch <br /> ® 1-Microwave dish - Comscope WHP6-65-P1A/K, 6 ft., 167 or 157 ft., [Chatham, <br /> Camden] <br /> • 1-Microwave transmission line — EWP63S jacketed, approx.1" x 2" elliptical <br /> waveguide <br /> Site Contact: Mr. James Davis, Chief Engineer, WCHL 919-271-4133, jwdc @nc.rr.com <br /> August 30, 2013 Page 9 of 51 <; <br /> 0 <br />
