TOOL REQUIRED FOR ASSEMBLY: Screwdriver, 11/32 nut driver or wrench, 7/16” and1/2” socket or
end wrenches, measuring tape.
1. Locate boom sections #1 & #2.
ASSEMBLING THE HORIZONTAL ELEMENTS
2. Lay out the elements by “H” length and position as shown in the DIMENSION SHEET. Start with
the reflector (longest) element. Balance it on your finger to find rough center and push on a black
button insulator to about 1/2” off center. Push the element through the hole in the boom and install
the second button, snugging it up into boom. DO NOT BOTHER CENTERING the element at this
time and DO NOT INSTALL the stainless steel shaft retainers yet. It is easier to do it after all the
horizontal elements are installed in the boom.
3. Install the 3/16” rod DRIVEN ELEMENT as you did the reflector. Then continue with the installation
of the DIRECTORS.
Note that the Director Elements MAY not consistently diminish in length from
rear to front, so pay close attention to length and position.
4. Now begin centering the elements. Use a tape measure to EQUALIZE, within 1/32", the amount
the element sticking out on each side of the boom. Once you have all the elements centered, sight
down the element tips from the rear comparing each side. Correct any obvious misalignments.
5. Stainless steel SHAFT RETAINERS lock the elements in place. They should always be used for
permanent and long term antenna installations. For portable or temporary use, the button
insulators are adequate for holding the elements and the retainers may be left off.
To install the stainless steel SHAFT
RETAINERS, use thumb and forefinger to
hold the retainer over the end of the PUSH
TUBE (3/8" x 3" tube, supplied in the kit),
internal fingers on retainer dished into tube.
HOLD THE ELEMENT FIRMLY TO
PREVENT IT FROM SLIDING OFF
CENTER and press the retainer onto the
element end and continue until retainer
butts on insulator button. Locking pliers,
lightly
clamped up against opposite button insulator will help maintain center reference (if
you push the first retainer too far, remove element from boom, push retainer completely off the
element, and start over). Install another retainer to the opposite side of the element. Continue
installing retainers until all elements are secured.
6. Mount the
HORIZONTAL
DRIVEN ELEMENT BLOCK / ROD ASSEMBLY to the
TOP
of the boom
using a single 8-32 X 1-1/4" screw. Orient the block with the two balun connectors facing to front.
7. Install the 8-32 x 1/4” set screws (internal Allen head - tool supplied) into the SHORTING BARS.
Slide the bars onto the 1/8" Driven Element Block Rods and the 3/16" driven element rod. Position
the Shorting Bars as shown on the Dimension Sheet, with the given dimension between the outer
face of the driven element block and the inner face of the shorting bar. Align the bars with each
other and tighten the set screws.
ASSEMBLING THE VERTICAL ELEMENTS
8. Repeat steps #2 through #5 to install the Vertical elements, using the Dimension Sheet as your
guide to lengths and spacing. Note: The vertical element set is shifted forward on the boom by 1/4
wavelength. This increases isolation between element planes, improving circularity and ease of
phasing / matching the two element sets.
