ASSEMBLY INSTRUCTIONS
1) Unpack antenna and locate the hardware package. If the antenna is shipped in two
pieces, remove Director 9, Connect the two boom pieces together at alignment marks. Re-
install D9 and tighten 4-40 nut to secure boom.
2) Straighten any misaligned elements and tighten hardware if necessary. But do not
touch the gold colored (brass) loop or the loops on either side of it, as these have been
factory adjusted.
3) If the boom-to-mast "L" bracket isn’t already attached to the bracket, do so now with the
hardware provided. (See diagram on opposite page. Polarization may be easily adjusted by
loosening the two hose clamps. Hydrogen line radiation is mostly randomly polarized.)
(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 for less than 1.5:1 at the factory. Additional
tweaking can be accomplished by adjusting the distance between the driven element and R1
and D1, or by slightly 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.
