Cupertino, CA 95014, for use with a federally licensed amateur radio station and show this installation to be in full compliance with City of Cupertino Municipal Code Chapter 19.108. The use of these antennas and supporting tower is exclusively for amateur radio operations(also known as HAM radio). The station is operated within the FCC part 97 rules. The station is used for low-power hobby type communications that include both local contacts and global contacts that bolster international good will. There are a number of drawings that will help to visualize the proposed changes. The wind load analysis has been included to show that careful consideration to engineering and safety are of paramount concern. LOCATION CONSIDERATIONS The following items were considered in locating the antennas and support structure: 1) Ensure that any support structure failure will not cause the antenna or the structure to touch power lines. 2) Ensure that any support structure failure will result in minimal risk to normally occupied areas of the yard. . 3) Locate the structure close to the operating position of the station to minimize feed line length. 4) Use the house to strategically distribute tower loads to minimize the size and number of required guy wires and guy supports in order to maximize aesthetics. In this installation, no - guy wires are utilized. DESIGN CONSIDERATIONS NOV 513 2002 J The following items were considered in designing the antenna support structure: By 1) Sustained winds above 90 mph will cause antenna and mast bending failures that will lighten the tower wind load to reduce the chance of a catastrophic tower failure. Winter conditions in this area are not conducive to ice build-up. No ice loading was factored into the design for load analysis. 2) Supports have been designed so that removal of these items, in the event that the house is sold, will not leave any"eye-sores"to contend with. 3) The height was chosen with several factors in mind. r���� v� ECyrD BsIIJJ JJ 3 02- a) To be below the height which would require City of Cupertino permitting/variance., b) To comply with FAA height. �- -Dr T.

ABSTRACT The stress loading herein uses the "method of joints"type of analysis and is presented in load as pounds of force in bending moment.All joints are considered simple single point cantilevers and use conventional load polarities in terms of tension and compression and are expressed as foot pounds. Only first order load distribution is used to ensure an adequate over design and also to ensure that the supporting members are not stressed beyond their modulus of elasticity (maximum allowable load). ASSUMPTIONS AND FACTORS Below is a list of assumptions and factors used in this analysis. 1) The antenna manufacturers' load ratings are accurate and true. 2) Failures are wind related and antennae failure will occur first. 3) The design consideration is 80 mph wind loading. • 5) The area is subject to no ice build up during the winter. 8) Use EIA wind loading of 20 pounds/square ft. of rated antenna area for 80 mph. CRITICAL LOAD MEMBER DEFINITIONS Load members are identified on the drawing as having an [n]designation, whereas, "n" is a number identifier. Below is a description and area value of each critical load member. oa 1 -Area = 1.5 square ft. as typical anticipated wind loading value of directional rglenna!r I 2-Area = 0.1 square ft.wind loading of 2'exposed mast and elevation rotator. NOV 13 2002 3-Area = 1.5 square ft.wind loading of Glen Martin RT-938 roof mount tower. By CRITICAL LOAD POINT DEFINITIONS Critical load points were determined as point of failures of the antenna support structure and do not preclude the failure of the antennas. Load points are identified on the drawing as having an {x)designation, whereas, "x"is an alphabetic letter identifier. Below is a description each critical load point. A-The points where the roof mounted tripod are attached to the roof. • B-The point where the mast engages the supporting tower. George Flammer Page 4 11/3/2002 C -The point where anticipated antenna is mounted to the vertical mast. D—Center point of the wind load represented by the Glen Martin RT-938 tower itself. • LOADING 1) Determine static load for each load member at design wind load of 80 mph. SL(n)= square ft of(n)'20 SL(1)= 1.5'20= 30.0 SL{2) =0.1 '20= 2.0 SL{3)= 1.5'20= 30.0 2) Determine bending moment at point(A)for each load member. SM(n)_ (SL{n)'length in feet from A) + SL(n). SM(1)= 30.0' 10.0= 300.0+ 30.0= 330.0 SM(2)= 2.0' 10.0= 20.0 +2.0= 22.0 SM(3)= 30.3= 90.0+ 30.0= 120.0 (assume CG @ T) 3) Determine final bending moment(since we assume there will be no ice loading) bending • moment at point(B). FM(A)= SM(1)+ SM{2)+ SM(3) FM(A)= 330.0+ 22.0+ 120.0 = 472.0 4) Determine maximum bending moment at points{A,...4). FM(A,)= FM(A)/4 FM(A,)=472.0/4= 118.0 (3 in tension, 1 in compression) [pi'n-el V 1CONCLUSION Both compressive and tensile loads are well within design limits for 2as installed per Figure 2..
