User manual CUSCRAFT A148-10S

[. . . ] YOU MUST INSURE THAT NEITHER PEOPLE NOR PETS CAN COME IN CONTACT WITH YOUR ANTENNA WHILE IT IS IN OPERATION. ALSO, SINCE THE EFFECTS OF EXPOSURE TO RF 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. If you use volunteer helpers be sure that they are qualified to assist you. [. . . ] Make certain that everyone involved understands that you are in charge and that they must follow your instructions. If you have any doubts at all employ a professional antenna installation company to install your antenna. MOUNTING The A148-10S mast mount bracket will take up to a 1-1/2" (3. 8 cm) O. D. A 1-1/4" (3. 17 cm) television type tubing is satisfactory for any of the single beams. A good heavy-duty antenna rotator will provide the best service and longest life. To keep possible interaction to minimum, place your antennas as far apart as you can. Keep the mast mount bracket on the opposite side of the boom from the elements. See page 5 for suggested dual and quad array configurations. SYSTEM GROUNDING Direct grounding of the antenna, mast and tower is very important. This serves as protection from lightning strikes, static buildup and 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. Attach the entire driven element assembly shown below to the boom with hardware provided referring to figure D for the proper location. Slide the poly tube (PT) on the Reddi-Match assembly over the rod (RR) up to the Ce FIGURE B-2 nte flattened end of that rod (figure B-2). Adjust to the dimensions r of An indicated and tighten all connections. Be sure that the connecten 11 Poly Tube na tor is pointed towards the center of the boom and the Reddi41 Match assembly is parallel to the element above. The cutting tolerance on these elements is ±1/16" (. 16 cm). The elements are progressively shorter as you proceed toward the front end of the boom. Attach each element to the boom per figure C referring to figure D for proper location. Poly tube on Reddi-Match should be touching the flared rod end. 11 41 BOOM 53 TABLE A ELEMENT LENGTH KEY NO.
