Orange County NC <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 Tower <br />Engineering Professional's opinion that the tower would fail the most current TIA/EIA <br />guidelines. Therefore, a structural analysis on this tower at this time is not <br />recommended. <br />Alternate locations in the same area as the WCHL towers should be investigated. <br />800 MHz RF coverage has been predicted from this site, and is shown in Figure 1. <br />Figure 2 is a representation of the previous 800 MHz portable talk -in coverage. <br />2.1.4.1 Site /Tower Details <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 '/4 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 iwdc(a�nc.rr.com <br />August 23, 2013 Page 9 of 37 <br />196 <br />
