TOOL REQUIRED FOR ASSEMBLY: screwdriver, 11/32 nut driver or wrench, 7/16” and1/2” socket or end
wrenches, measuring tape.
ASSEMBLING THE HORIZONTAL ELEMENTS
1. Lay out the elements by “HORIZONTAL” length and position as shown 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. 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.
2. 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 do not consistently diminish in length from rear to front, so pay
close attention to length and position.
3. Now begin centering the elements. Use a tape measure to EQUALIZE 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. Look for any obvious discrepancies and correct if found.
4. 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 to 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.
5. 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 rear.
6. Install the 8-32 x 1/4” set screws (internal Allen head - tool supplied) into the SHORTING BARS. Slide the
bars onto the 1/4" Driven Element Block Rods and the 3/16" driven element rod.
Position the Shorting Bars
as described on the dimension sheet.
Align the bars with each other and tighten the set screws.
ASSEMBLING THE VERTICAL ELEMENTS
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.
7. Repeat steps #1 through #6 for the Vertical elements, using the Dimension Sheet as your guide to lengths
and spacing.
INSTALLATION OF THE VERTICAL DRIVEN ELEMENT BLOCK DETERMINES THE CIRCULARITY OF
THIS ANTENNA. THE ORIENTATION OF THE BLOCK FOR RHC - RIGHT HAND CIRCULARITY, IS
SHOWN ON THE DIMENSION SHEET.
8. Viewed from the rear of the boom (rearmost Reflector HORIZONTAL), the VERTICAL Driven Element Block
mounts to the LEFT hand side of the boom with the two Balun connectors oriented to the FRONT. Secure
with 8-32 x 1-1/4” screw. Install the Shorting Bars as in step #6.
