User manual CUSCRAFT A148-10S

[. . . ] There is a master parts list on page 2. 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. [. . . ] Keep the mast mount bracket on the opposite side of the boom from the elements. This will help to minimize pattern distortion from the mast. 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. 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 5. After the antenna is completely assembled, verify dimensions and element spacings for accuracy. Then, return to the section below for final tuning. TUNING PROCEDURE The A148-10S does not normally require tuning after assembly. However, if you wish to check the VSWR before installation, please observe the following procedures. Slide the tuning strap (125) onto the driven element (EB) and secure loosely with screws (79), nuts (11) and lock washers (41). Slide the Reddi-Match assembly through the tuning strap. Connect the flattened rod end to the screw on the connector bracket (CB) with nut (11) and washer (41). 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. Check all element lengths using table A. 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. [. . . ] Attach the connector to the Reddi-Match. Apply the remaining silicone to the outside of the connector. Slip the vinyl boot over the connector and against the mast bracket for a weather tight connection.
