The proposed Lake Cedar Group Supertower increases Radio Frequency Radiation levels in nearby neighborhoods








Did you Know...
	The proposed Lake Cedar Group Supertower will increase Radio Frequency Radiation levels in nearby neighborhoods!


	Calculations made by Jefferson County’s independent RF expert, Lake Cedar Group, and CARE engineers all showed that RF levels will increase in nearby neighborhoods if the Lake Cedar Group Tower is built. (Hearing record 12112, 2622,1700,1879-1908). According to the testimony of Jefferson County’s RF expert, “All these places that were south, to the north and to the east increased differentially.” (Hearing record at 12112)
	To the right are figures from Lake Cedar Group’s own RF report, comparing RF levels calculated under the current conditions, and calculated levels if the Lake Cedar Group tower were to be built. Circled in white are points with INCREASED RF EXPOSURE if the Lake Cedar Group tower were to be built. Note that even areas to the west of the tower would experience RF increases. While the Lake Cedar Group RF report does have some errors, it does confirm that the proposed tower would result in RF increases in neighborhoods to the south of the tower, as was found by both CARE engineers and Jefferson County’s independent RF expert. The Lake Cedar Group RF report did not address levels to the east in Golden, however calculations by Jefferson County’s RF expert (Hearing record at 12108) showed that the proposed Lake Cedar Group tower would cause RF levels to increase at the Colorado School of Mines in Golden. Calculation Errors Very near the towers, the comparison in the Lake Cedar Group RF report shows a significant reduction in RF levels. The red and pink high RF areas are gone in Figure 7. A point near the FOX tower has an RF level of 100.3% Maximum Permissible Exposure (MPE) before, and only 67.6% MPE with approval of the LCG proposal. This would be a 32.7% decrease in MPE.

		The areas South and Southwest of the proposed tower site are highly populated areas!

	But, There is a Problem... The existing members of Lake Cedar Group do not currently contribute more than 5% MPE on Lookout Mountain. It is for this reason that Lake Cedar Group member stations have not been required by the FCC to take corrective action to cure RF overages on Lookout Mountain. Lake Cedar Group spokesman Marv Rockford even cites the awareness of Jefferson County’s RF expert regarding this fact in his closing statement (hearing record at 12073). The fact that the three Lake Cedar Group members currently on Lookout Mountain contribute less than 5% MPE each means that if all three member stations of Lake Cedar Group were to turn off their existing transmitters completely, the maximum RF reduction would be 15% MPE, assuming each Lake Cedar Group member station contributed 5% at the same location. It is physically and mathematically impossible for the Lake Cedar Group proposal to produce a 32.7% decrease in MPE on Lookout Mountain. Lake Cedar Group’s RF report states,“A comparison only of Figures 6 and 7 indicate changes due solely by the LCG proposal.” (Hearing record at 1700) If the members of Lake Cedar Group can’t produce a 32.7% decrease in MPE levels by turning their existing transmitters off completely, how can they produce this reduction by adding 5 more high power transmitters to Lookout Mountain? The answer is, of course, that they can’t. Clearly something is wrong with the calculations! The complete calculations and parameters used to perform the calculations of this Lake Cedar Group RF report have never been revealed, and we do not know the source of this error. All we know is that the claimed RF radiation reductions near the towers are exaggerated in this report. To read detailed information about RF Calculations, click here...
	Why doesn't Lake Cedar Group’s directional antennas lower RF levels for most people? Several factors combine that would cause RF increases in most neighborhoods surrounding the proposed tower. The “directional” antenna patterns proposed by Lake Cedar Group are not really so directional. The antenna heights on the proposed tower are low with respect to surrounding residences. The Effective Radiated Power of the proposed Lake Cedar Group tower would be more than 13 times higher than that of the existing Lake Cedar Group stations on Lookout Mountain.
