Orange County NC Radio Communication Tower and System Infrastructure Upgrade RF Coverage and Sites /Towers Contact with the tower owner has been established through the Chapel Hill Police Department, and discussions with the tower owner have taken place. A physical inspection of the tower revealed that it was installed in 1968. Since the tower uses hollow tube steel legs, a structural analysis would need to include inspection of the inside of the tubular tower legs to check for the amount of corrosion. Also, it is FE's subcontractor's opinion that the tower would fail the most current TIA/EIA guidelines. Following discussion with Orange County, it was agreed that a structural analysis on this tower at this time was not to be performed. Alternate locations in the same area as the WCHL towers should be investigated. At the direction of Orange County, FE reviewed the possible alternate locations for a site in this area. A site approximately 1,000 ft. to the south of WCHL could possibly be pursued. This alternative site is described in Section 2.1.5. FE predicted 800 MHz RF coverage for this site, and is shown in Figures 3 through 8, which can be found in Section 2.1.7.
