ASSEMBLY INSTRUCTIONS
1)
Unpack antenna and locate the two preassembled antenna sections and the hardware
package. The boom is broken between elements D22 and D23. Remove D22 from the boom
piece and slide boom pieces together to alignment marks. Replace D22 and retighten. (D22 is
the element approximately 0.5 inch from the end of the boom section; it will only fit together
one way.) 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.
