User manual CUSCRAFT R5

[. . . ] YOU MUST INSURE THAT WHILE THE R5 IS IN OPERATION NEITHER PEOPLE OR PETS CAN COME IN CONTACT WITH ANY PORTION OF YOUR ANTENNA. ALSO, SINCE THE EFFECTS OF EXPOSURE TO RF FIELDS ARE NOT FULLY UNDERSTOOD, LONG TERM EXPOSURE TO INTENSE RF FIELDS IS NOT RECOMMENDED. THERE IS A WARNING STICKER WHICH MUST BE ATTACHED TO THE BOOM AS SHOWN IN FIGURE E. MOUNTING The mast mount bracket will accommodate up to a 2" (5. 1 cm) mast. A 1-1/2" OD (3. 8 cm) or larger heavy wall tubing mast should be used. [. . . ] A good heavy duty antenna rotator will provide the best service and longest life. To keep possible interaction to a minimum, place your antennas as far apart as you can. The R5 provides excellent gain, clean pattern and low VSWR across the entire 2 meter band. 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. Push the end caps (131) onto the ends of the boom. KEY BA BB BC 11 41 123 131 411 P/N DESC.
