The document review was for the 2000 Hemphill design and the recent tower mapping completed by General Dynamics. The purpose of the review was to determine if sufficient capacity exists in the monopole to allow the proposed US Cellular CDMA panel antennas to be installed without need for an additional monopole analysis. The 80 -foot tall monopole is constructed of several stacked pipe sections. The monopole was originally designed for 75 mph wind loading, slightly in excess of the local County requirements, with %2 -inch of radial ice loading. It was also designed to support cellular arrays at two platforms on top of the monopole and included (2) microwave antennas located on the monopole. The existing antenna loading consists of (9) top -mounted cellular panels as noted in the tower mapping report. By inspection, it is obvious that the monopole has sufficient reserve capacity to support the proposed US Cellular CDMA panels with no need for analysis, upgrade, or any other structural concerns. We recommend that the US Cellular antennas be installed as proposed and the antennas database for the tower be updated accordingly. We have enjoyed working with you on this project. If you have any additional questions, comments, or concerns please feel free to Cali.
