Tools handy for assembly process: screwdriver,
11/32”
spin
-
tite or socket,
7/16”
and
1/2”
end wrenches /
sockets, measuring tape.
1.
Lay out the elements by length and position as shown the DIMENSION sheet. Start with the
REFLECTOR (longest) element. Balance on finger to find rough center and push on a black button
insulator to about
1/2”
from center. Push the element through the holes 10" from the rear of the boom
and install the second button, snugging it up into boom. DO NOT BOTHER WITH ACCURATELY
CENTERING the element at this time and DO NOT INSTALL the stainless steel SHAFT RETAINERS
yet. This is easier to do after all the elements are installed in the boom. Install the
3/16”
rod DRIVEN
ELEMENT as you did the reflector and then the DIRECTORS.
2.
Now accurately center the elements. Use a tape measure to EQUALIZE the amount the element
sticking out on each side of the boom. Begin installing the stainless SHAFT RETAINERS. Use thumb
and index finger to hold a retainer over end of the 3/8 x
3”
push tube (retainer dished into tube). Hold
the element firmly and start the retainer onto the rod by applying pressure with the push tube. Push
the retainer until up tight against the button insulator (Locking pliers,
lightly
clamped up against
opposite button insulator will help maintain center reference and keep you from pushing the first
retainer too far). Repeat for the opposite side. Continue installing retainers until all elements are
locked in place.

Orient the block with feed connector facing the rear and balun connectors facing forward.
4.
Attach balun to the Block and tighten the connectors
gently
using a 7/16" end wrench. A lot of torque
is unnecessary. Form the balun close to the boom and secure with a nylon cable ties. Ties should be
snug but not crushing or kinking the coax.
