User manual CUSCRAFT R5

[. . . ] If you have any doubts at all, employ a professional antenna installation company to install your antenna. LOCATION Location of the antenna is very important. Surrounding objects such as trees, power lines, other antennas, etc. To minimize the effects of surrounding objects, mount the antenna as high and in the clear as possible. If metal guy wires are used, they should be broken with strain insulators. [. . . ] It can be mounted either horizontally or vertically. VERTICAL (FM): If you plan to mount the R5 for vertical polarization, best results can be obtained by mounting the antenna at the top of the mast. Note that element #6 is 3" (7. 6 cm) from the edge of the mast mounting plate as shown in Figure D. Install the R5 with the elements on the side of the mast opposite from the mounting plate. A vertically polarized R5 will have a VSWR of under 2:1 from 144 to 146 MHz. HORIZONTAL (CW/SSB): Mount your R5 horizontally and as high as possible, with the boom-to-mast plate between elements 6 and 7 as shown in figure D. SYSTEM GROUNDING Direct grounding of the antenna, mast and tower is very important. This serves as protection from lightning strikes and static buildup, and from high voltage which is present in the radio equipment connected to the antenna. A good electrical connection should be made to one or more ground rods (or other extensive ground system) directly at the base of the tower or mast, using at least #10AWG ground wire and non-corrosive hardware. For details and safety standards, consult the National Electrical Code. You should also use a coaxial lightning arrester. Cushcraft offers several different models, such as LAC-1, LAC-2 and the LAC-4 series . ASSEMBLY Assemble your antenna by following the directions and illustrations in steps 1 through 6. Join booms with screw (123), washer (41) and nut (11). Refer to the dimensions in figure A to be sure that the proper tube ends are joined. Push the end caps (131) onto the ends of the boom.
