However, it is incumbent on the builder to exercise care while handling antenna kit parts. As a minimum, it is recommended that the builder wear gloves and eye protection while assembling the antenna to aid in the prevention of injury. WARNING: INSTALLATION OF THIS PRODUCT NEAR POWER LINES IS DANGEROUS. FOR YOUR SAFETY FOLLOW THE INSTALLATION DIRECTIONS. Elements will be called out by their position on the boom, R = reflector, DE = driven element and Delement number = director. The director’s number is relative to the DE element with D-1 nearest the DE. Director elements are identified by color strips, which are affixed to one end of an element. The numbering system used is the same as for all electronic components: ColorDigit= Black 0, Brown 1, Red 2, Orange 3, Yellow 4, Green 5, Blue 6, Violet 7, Gray 8, White 9 ASSEMBLY INSTRUCTIONS ( ) ( ) ( ) ( ) ( ) Your antenna is furnished with a tube of NOALOX®. Before assembling the boom sections, apply a thin coat of NOALOX® to the end of the boom section to be inserted. NOALOX® is an anti-oxidant compound and will prevent corrosion build up between the telescoped boom sections, as well as providing a lubricant to ease in assembly. Locate the rear boom section (1.25" diameter with a ½" hole drilled thru it) and the center boom section (1.375" diameter). Match the color code (BLACK to BLACK) of these two boom sections and insert the rear boom section into the center section. Align the small holes of these two sections with one another and fasten the sections with a #8 x 1 3/4" stainless screw and nut with integral lockwasher. Insert the front boom section into the front of the center boom section once again matching the color code (BROWN to BROWN) and fasten with #8 x 1 3/4" stainless hardware. 3 ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) The boom sections should be further secured by placing a #16 stainless hose clamp over the points where the boom sections telescope. The ends of the boom sections have been slotted so that the hose clamps can compress the tubing. Tighten the hose clamps securely. Locate the shortest 1/4" diameter element (D-10). Measure from either end of the element and mark the position of the keeper, see Element Table in Figure 1A for the correct distance. Using the provided keeper installation tool, slide a keeper onto the element until it is within 1 mm of the mark, (see Figure 2). Do not slide the keeper too far onto the element or it will be necessary to slide the keeper all the way across the element to remove it. The keepers can not be moved backward. Place a black Celcon insulator in one of the holes in the boom at the position of the D-10 element and insert D-10 element thru the black Celcon insulator and boom. Slide a second black Celcon insulator over the other end of D-10 element and install a keeper (see figure 2). Using the provided keeper push tool CAREFULLY work keeper inward until the element is tight and centered. If you tighten the keepers and the element is not centered it will be necessary to break one of the keepers to reposition the element. Extra keepers are provided with each kit in case it becomes necessary to re-center an element. Small errors of 1 or 2 mm will NOT degrade the performance of the antenna. ERRORS OF 4 OR 5 MM SHOULD BE CORRECTED. Using the same procedure, install the balance of the elements, D-9 to D-1 and the Reflector. Follow the dimensions shown in the Element Table, Figure 1A, to identify the proper elements and dimensions. Refer to Figures 4 & 5 and assemble the driven element and T-match as outlined in the following steps. Locate the ½" diameter driven element, two 3/8" T-Match Rods, and coax balun/phasing line. Insert the driven element thru the boom and align the #8 holes in the element with the #8 hole in the boom. Refer to Figure 4 and place a #8 star lockwasher on the #8 X 1 1/2" stainless screw and insert the #8 screw through the 3/8" hole in the boom through the driven element. Place the Omega shaped bracket with the Delrin insulators installed on the #8 screw and align perpendicular to the boom. Place the L-shaped N-Connector bracket with N-Connector installed on the #8 screw. Make certain the N–Connector is facing toward the front of the antenna. Refer to Figure 4 and place a #8 star lock washer on the # 8 screw and slide one ground lug, connected to the shield of the phasing line, onto the screw. Now slide a #8 star lockwasher onto the screw, and the second ground lug, from the shield of the other end of the phasing line. Place a #8 nut w/integral lock washer on the #8 screw and tighten the nut one full turn beyond the point it becomes firm. Place the black 3/8" plug in the hole opposite the Omega bracket. Locate the two 3/8" T-Match Rods. 4 ( ) Pass a #6 x 1/2" screw through the lug on one of the center conductors of the phasing line. ( ) Install a #6 star lockwasher and then pass the screw through the hole in one of the TMatch Rods. ( ) Screw the screw firmly into one of the black Delrin support insulators. ( ) Refer to Figure 5 and install a shorting block on the outer end of the T-rod and driven element. ( ) Dress the phasing line toward the rear of the antenna. ( ) Align the T-rod until it is parallel to the driven element. Do not secure the shorting block at this time. Read before proceeding with the next step. If more than one antenna is to be used, be certain that the coax center conductor always feeds to the same side of the driven element for all antennas. For vertical stacking the lower antennas may be mounted with coax feed upward but be certain that you reverse the feed direction of the T-match, so that all antennas are fed to the same side of the boom. ( ) Pass a #6 x 1/2" screw through the lug attached to the braided wire center conductor of the N-Connector. ( ) Slide on a #6 star lockwasher then pass the screw through the lug on the remaining center conductor of the Balun/phasing line. ( ) Slide another #6 star lockwasher onto the screw and then pass the screw through the second T-rod and screw it into the second black Delrin insulator. ( ) Again refer to Figure 5 and install a shorting block between the outer end of the T-rod and the driven element. Do not secure the shorting block at this time. ( ) Check and make certain that both T-Match Rods are parallel to the driven element and the shorting blocks are perpendicular to the rod and element. ( ) The outer edge of the shorting blocks should be 12.5 mm for 144 MHz or 4.5 for 147 MHz from the end of the T-Match rod. If the shorting blocks are not at a distance of 12.5mm or 4.5 mm adjust their location and tighten the #8 machine screws. ( ) In the next step be very careful not to bend or twist the balun coaxial cable otherwise damage will occur to the balun cable which is not covered by warranty. ( ) Use the #6 x 3/8" sheet metal screw and black cable clamp to fasten and dress the phasing line to the rear of the boom, again being careful not to twist the cable. ( ) Attach the boom to mast plate to the boom midway between elements D-5 and D-6 (see Figures 1B and 3). Use 1 3/8" saddles and the 1-1/2" SS U-bolts with 1/4" stainless nuts and lockwashers. The antenna will be front heavy at this point but the weight of the feedline, when attached, will cause it to be balanced. If using multiple antennas in an array, be certain that all mounting plates are at the same location. When attaching the antenna to your mast, use the 5/16-18 U-Bolts, associated hardware and saddles provided (Refer to Figure 3). ( ) Place the 1 1/4" RED end caps on the ends of the antenna boom. Place the 1/2" RED end caps on the DE and the 3/8" RED end caps on the T-Match rods. 5 ( ) At this point the antenna can be tuned for final adjustment if a directional watt meter or return loss bridge is available. Support the antenna about 8 ft. above the ground and point it in a direction clear of anyobstructions for a distance of 100 ft. minimum. DO NOT USE A POWER LEVEL ABOVE 10 WATTSWHILE MAKING ADJUSTMENTS. DO NOT STAND IN FRONT OF THE ANTENNA. THE RF LEVEL WILL BE DANGEROUSLY HIGH. Slide the shorting blocks in or out in very small increments until the best VSWR is obtained. The VSWR should be less than 1.5:1 at 144 MHz or 147 MHz with the dimensions given. Coat the driven element, insulators, standoffs, and all keepers with a clear weather proof lacquer. KRYLON #1301 or 1302 is highly recommended. Three or four coats will protect the antenna from corrosion for many years. Do not coat the antenna until final swr measurements have been made. Stacking distances for optimum gain to noise temperature ratio are: E-plane1 l ft 6in H-plane10 ft 6in WARNING: INSTALLATION OF THIS PRODUCT NEAR POWER LINES IS DANGEROUS.
