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 ASSEMBLY to the
HORIZONTAL
DRIVEN ELEMENT BLOCK / ROD
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.
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
at 1/8" from the tips of the 3/16" rods.
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.
8. Repeat steps #2 through #5 for the Vertical elements, using the Dimension Sheet as your guide to lengths
and spacing.
INSTALLATION OF THE
VERTICAL
DRIVEN ELEMENT BLOCK DETERMINES THE CIRCULARITYOF
THIS ANTENNA. THE ORIENTATION OF THE BLOCK FOR RHC - RIGHT HAND CIRCULARITY, IS
SHOWN ON THE DIMENSION SHEET AND DRAWING AND DESCRIBED BELOW:
9. Viewed from the rear of the boom (rearmost Reflector HORIZONTAL), the VERTICAL Driven Element Block
mounts to the RIGHT hand side of the boom with the two Balun connectors oriented to the REAR. Secure
with 8-32 x 1-1/4” screw. Install the Shorting Bars as in step #7.
10. Before installing the Baluns and Matching / Phasing Harness. Attach Baluns and Phasing lines to the Driven
Element Blocks and Junction Block as shown on the Dwg. Tighten the connectors
gently
using a
7/16"
end wrench. A lot of torque is unnecessary. Depending on model and polarity, the Vertical balun may loop
around another element. This is normal. Form balun coax until it is close to the boom and secure with a
nylon cable tie. Also secure the other balun and the matching / phasing harness coax with cable ties. Ties
should be snug but not crushing or kinking the coax.
