Tools Required For Assembly; Assembling The Horizontal Elements - M2 Antenna Systems 436CP42UG Assembly Manual

436CP42UG ASSEMBLY MANUAL
TOOLS REQUIRED FOR ASSEMBLY: Screwdriver, 11/32 nut driver or wrench, 7/16" and 1/2" socket or end
wrenches, measuring tape.
1. Assemble the boom using 8-32 screws and locknuts to join sections. Use screw lengths 1/4" longer than the
larger of the two boom sections to be assembled (1-/34" hardware for 1-1/2" boom section, etc.)

ASSEMBLING THE HORIZONTAL ELEMENTS

2. Lay out the elements by "H" 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. Push the element through the holes 1/2" from the rear of 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.
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 do 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 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.
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 rear.
