ASSEMBLYINSTRUCTIONS
1) Unpack the antenna and locate the hardware package. Some antennas are shipped in
two sections, in which case the boom is broken between directors 25 & 26. Remove D24 and
D25 from the rear boom section and slide the two boom pieces together. Align the elements.
Replace D24 & D25 and retighten.
2) 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.
3) Attach the feed line, and tape it to the bottom of the boom. . The connector should be
sealed with silicone RTV or equivalent.
4) Straighten any misaligned elements and re-tighten if necessary.
5) The antenna SWR has been adjusted at the factory for less than 1.5:1 mismatch.
Additional tweaking can be accomplished by changing the shape of the driven element slightly
and by adjusting the distance between the driven element andR1 and D1. R1 is the reflector
closest to the driven element.
6) If antennas are to be stacked, see "Instructions for Stacking Loop Yagis".
