Assuming simuhaneou S <br /> operation of all tiransmitters, mau3m sm effective radiated power at the site is 2200 want Gives <br /> the height above ground level of the trans:mitting antennas and the directivity of the t:aasanittiag <br /> antennas in the vertical plane, the estimated exposure level six feet above ground level at the <br /> tower base is less than 0.0003 mW/em=, which is equivalent to 0.01 percent of the MPE for <br /> controlled environments and 0.05 percent of the WE for uncontrolled environments. <br /> Conclusion <br /> RFR exposure levels measured on the ground and inside the equipment shelter at the <br /> KNKA293 site were non than one hundred times less than the protection guide.: set forth in <br /> ANSI 095.1-1982 and the applicable MM set forth in 095.1.1992 It is extremely Maly that <br /> a more sensitive electromag monitor would show the wgxm n levels to be thou ands of times <br /> less than the maromnms established by the standards. Further, public access to the site is <br /> restricted, fits, by a fence enclosing the self-storage complex within which the cellular site <br /> located, anct second, by a fence enclosing the tower base. <br /> A any changes to the transmission system, routine measurement of <br /> elearomagnedc field strengths at the K NKA293 site would serve no purpose other than to prove <br /> well established laws of physics by demonsorating that no change in the transmission system <br />
