1. Start by laying out the boom sections using the DIMENSION sheet as a guide. Use 8-32 X 1-1/4
screws and locknuts to join sections. Sections may be swaged to fit each other.
2. Lay out the elements by length and position as shown the DIMENSION sheet. Start with the
reflector (longest) element and push on a black button insulator to about 1/2” from 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 WITH ACCURATELY CENTERING the element at this time and
DO NOT INSTALL the stainless steel internal locking “KEEPERS” yet. This is easier to do after all
the 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 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. Begin installing the stainless “keepers.” Use thumb and index finger to hold a keeper over end of
the 3/8 x 3” push tube (keeper dished into tube). Hold the element firmly and start the keeper onto
the rod by applying pressure with the push tube. Push the keeper 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 keeper too far). Repeat for the opposite side.
Continue installing keepers until all elements are locked in place.
