ASSEMBLY INSTRUCTIONS

1) Unpack antenna and locate the two preassembled antenna sections and the hardware

package. The boom is broken between elements D16 and D17. Remove D16 from the boom

piece and slide boom pieces together to alignment marks. Replace D16 and retighten. The

booms are marked for your assembly.

2) Straighten any misaligned elements and tighten hardware if necessary. But do not

touch R1, DE or D1, as these have been factory set for minimum SWR.

3) Attach the boom to mast plate to the boom with the hardware provided. Install the U-

bolts so that the mast comes up directly under the boom.

(Can be up or down) (Can be left or right)

4) Attach the feed line, and tape it to the bottom of the boom. The connector should be

sealed with electronic grade RTV or equivalent.

5) The antenna SWR has been adjusted at the factory for less than 1.5:1. Additional

tweaking can be accomplished by adjusting the distance between the driven element and R1

and D1, or by adjusting the shape of the driven element. NOTE: Do not attempt this

adjustment unless the proper equipment and qualified personnel are available.

6) If antennas are to be stacked, see "Instructions for Stacking Loop Yagis".

DO NOT, UNDER ANY CIRCUMSTANCES, APPLY ANY TYPE OF SEALANT OR COATING TO THE

DRIVEN ELEMENT, T-ARMS OR CONNECTOR ASSEMBLY, OTHER THAN KRYLON®

CLEAR COAT. ANY OTHER COATING WILL ADVERSELY AFFECT THE SWR AND VOID YOUR

WARRANTY.
