. <br /> r <br /> NwrE NorthWest Tower Engineering <br /> g g <br /> Rucker Hill, Everett, WA Report No. 210621.13 April 22, 2021 <br /> The tower was found to fall within the Twist and Sway limitations for microwave antennas set <br /> forth in the TIA-222-G Standard for 3dB degradation in RF signal. Twist and sway values <br /> calculated at each dish location for 60-mph wind (3-second gust) were found to be within <br /> allowable values. Operating frequencies of 6 and 11GHz were assumed. <br /> Conclusion <br /> The tower meets the requirements of the TIA-222-G and TIA-222-H standards for the antenna <br /> configurations considered. No structural upgrades are required. <br /> Conditions of Analysis <br /> The analysis performed and the conclusions contained herein are based on the following <br /> assumptions: <br /> • The tower has been properly installed and maintained. <br /> • Steel grades for structural members are as listed above. <br /> • No x-ray, subsurface excavation, or other similar examination of the tower, foundation <br /> system, or welded connections was conducted. For portions of the tower and foundation <br /> system that were not visually accessible, no determination regarding the condition or <br /> adequacy was made. <br /> • All structural components of the tower including, but not limited to, structural members <br /> (legs, bracing, etc.), connection components (gusset plates, welds, bolts), guy wires, <br /> anchor arms, and foundations are in good condition. <br /> • Feed lines are arranged as shown in the attached cross section. <br /> • Proposed mounts will be as indicate in the appurtenance loading tables. <br /> Deviations to these assumptions may affect the analysis results. <br /> NorthWest Tower Engineering 5 www.nwtower.net <br /> 3426 Broadway,Suite 302,Everett,WA 98201 Tel 425-258-4248 Fax 425-258-4289 <br /> LDfiL <br />
