User manual CUSCRAFT 13B2N

[. . . ] Make certain that everyone involved understands that you are the boss and that they must follow your instructions. 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. To minimize the effects of surrounding objects, mount the antenna as high and in the clear as possible. [. . . ] 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. 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 13B2N does not normally require tuning after assembly. However, if you wish to check the VSWR before installation, please observe the following procedures. To prevent detuning the antenna, it should be tuned in place or at least 7 feet (2. 13 meters) above ground and clear of surrounding objects. Keep all metal obstructions such as guy wires and other antennas at least 10 feet (3. 05 m) away since they will nullify any adjustment and degraded performance will result. Run the coax cable from your transmitter to the area in which the antenna is going to be tested. When you read VSWR, be sure you move far enough away from the antenna so that your body does not effect the reading. If it is high, move both T-Match straps (125) by 1/4" (. 6 cm) either inward or outward and check the VSWR. Both T-match straps should be the same distance from the center of the driven element. If the VSWR improved, then continue moving the T-Match straps in the same direction. If the VSWR deteriorated then move the T-Match straps in the opposite direction. Tape the feedline to the boom and mast as shown in figure G. 1 13B2N MASTER PARTS LIST KEY 11 26 28 41 53 70 77 79 84 85 104 115 116 118 119 120 123 125 131 P/N 010011 190026 190028 011941 050053 190070 050077 010079 010084 010085 010104 050115 240116 010118 010119 010120 010123 200125 050131 DESCRIPTION QTY 8-32 stainless steel hex nut 22 7/8" (2. 2 cm) formed aluminum bracket 13 Aluminum half washer 12 No. 8 split lock washer 26 1/2" (1. 27 cm) black plastic cap 2 4" x 6" (10. 2 x 15. 2 cm) formed mounting plate 1 3/8" (. 95 cm) black plastic cap 2 8-32 x 1/2" (1. 3 cm) stainless steel machine screw 4 1/4" (. 64 cm) stainless steel lock washer 4 1/4" (. 64 cm) stainess steel hex nut 4 1/4" (. 64 cm) stainless steel flat washer 4 Vinyl Boot 1 Silicone Package 1 5/16" (. 79 cm) stainless steel hex nut 4 5/16" (. 79 cm) stainless steel lock washer 4 8-32 x 2" (5. 1 cm) stainless steel machine screw 12 8-32 x 1-1/2" (3. 8 cm) stainless steel machine screw 3 T-match strap 2 1-1/8" (2. 86 cm) black plastic cap 2 KEY 232 326 401 404 411 940 BA BB BC UM EA EB EC ED EE EF EG ET P/N 010232 290326 010401 010404 030411 360940 DESCRIPTION QTY 8-32 x 2 -1/2" (6. 4 cm) stainless steel machine screw 1 Danger label 1 1-1/2" x 3" (3. 8 x 7. 6 cm) stainless steel U-bolt 2 2-1/2" x 3" (5. 5 x 7. 6 cm) stainless steel U-bolt 2 1-3/8" (3. 5 cm) stainless steel worm clamp 2 No. [. . . ] Note that the rear of the mast clamp must be 3 inches (7. 6 cm) from element 6 as shown on figure D.
