BEFORE ASSEMBLY
GETTING STARTED BY GETTING ORGANIZED - Organize the tubing into groups, first by tube OD (Outside Diame-
ter) and then by length and check all against the parts list to make sure it’s all there. Notify us immediately if you are
missing anything.
Tools - You will need the usual assortment of small hand tools to assemble this antenna as well as quality black electri-
cal tape. We recommend the use of a mixture of WD-40 and lock graphite, or similar compound, to lubricate each and
every tubing joint and screw hole during assembly, the end of each element being placed into the boom and the boom
splice couplers.
Read - ead these instructions several times before starting the actual assembly process & until the process becomes
clear. efer to FIGS. 1, 2 & 3 as you read to develop the understanding of how the antenna is constructed.
Left and Right - Left and ight, as used in these instruction, are arbitrarily assigned.. Assembled in the mirror image,
the result is just as good. BUT, following the directions as stated will keep you organized and once started MUST be
followed.
Assembly Phases - The antenna will be assembled in 5 phases:
Phase Description After which you will have
1 Boom Section Preparation 10 prepared Boom Sections 6 feet long (5 identical pairs)
with the first tube of the elements attached.
2 Boom Section Splicing After which you will have 2 identical sub-booms 24 feet long
3 Boom Completion Spacers attached and booms secured atop each other
4 Element Build Out Completed antenna with elements attached
5 Attachments and Feedline Installation of BMI, shorting stub, balun,
antenna ready to go in the air
ASSEMBLY INSTRUCTIONS
This antenna has two sub-booms, one will be placed atop the other to form one structural boom with two separate elec-
trical paths. These sub-booms are machined so that the elements pass directly through them. There are intentionally
tight tolerances here, typically 1 or 2 thousandths of an inch, DO NOT FILE OUT THE HOLES MACHINED IN THE BOOMS.
ather, if you must, use a fine emery cloth applied to the element itself.
Lubrication and Protection - epeating here: We recommend the use of a mixture of WD-40 and lock graphite, or similar
compound such as Penetrox A, to lubricate each and every tubing joint and screw hole during assembly, the end of
each element being placed into the boom and the boom splices.
SALT AIR ENVIRONMENT? You need to seal each tubing joint with minimal amounts of tape, heat-shrink or similar seal-
ant. Note: Use absolutely no more of these materials than is needed. Excess on the outside of the tubes can cause an
unwanted shift in the velocity of propagation along the tube. Completely cover the protruding stainless steel boom hard-
ware with a sealant to avoid corrosion and resultant galvanic action that can cause electrical noise.
