35.7-4 ASSEMBLY MANUAL
7. Now adjust the ELEMENT SPACING to match the Dimension Sheet. Since the Driven element is fixed, use
it as the reference for setting the position of the Reflector, 52-1/2” to the rear. Then space all Director elements
forward, using the Driven element as the reference. Dimensions given are “center to center” and can also be
used “edge to edge” when working with a measuring tape. After setting spacing of each element, align it
parallel with the Driven Element and tighten the 1/4-20 x 1” bolt.
8. Attach the balun coil to the pair of connectors on the “T” match block. Secure balun with the nylon ties
supplied (ties should be snug, but not crushing cable). Bottom connector on block is for your 50 Ohm feedline.
9. Locate the balance point of the antenna and mount the BOOM TO MAST PLATE, 6” length horizontal.
Orient for desired polarity and secure with two heavy duty 2” U-bolts, cradles, 3/8” stainless lockwashers and
nuts. Two 2” U-bolts are supplied for attaching the antenna to the mast. If the feed connector will not be
accessible after installation, connect a feedline section now that reaches at least to the boom to mast plate.
10. This completes the ASSEMBLY. When the antenna is installed in position on the mast, the main feedline
can be attached. REMEMBER to support the feedline at the antenna boom exit point and on the mast. Allow
enough slack feedline to permit full rotation of the antenna.
