Separate the parasitic elements into two groups of vertical and horizontal
elements. Install one group (vertical or horizontal) at a time.
Locate the longest 3/16" diameter element (reflector). Slide on one of the
"button" mounting insulators, small end first. Push the insulator to the element balance
point. DON'T WORRY ABOUT THE EXACT LOCATION AT THIS POINT. Repeat this
operation for each of the remaining rod elements.
Pick up all the rod elements and settle them in your grasp on a flat smooth
surface. Starting with the longest rod, insert it through the end hole in the boom near
the driven elements. Next, move to the hole directly in front of the driven elements and
insert the next longest element. Continue inserting the next longest rod director in the
next hole, and the next, and the next, until all the rod directors are in place.
Now return to the reflector and slide on the second button insulator from the
opposite side of the boom. Visually center the element in the boom. Consult the
antenna Dimension Sheet and, using a tape measure, set the element position so the
element is centered in the boom. THIS CENTERING OPERATION IS VERY CRITICAL
FOR PROPER PERFORMANCE OF THE ANTENNA.
Move the next rod director and repeat the second button insulator installation and
centering operation. Continue until each rod director is fully mounted and centered.
Return to the reflector now and install the element keeper washers on each side.
BEFORE PUSHING THEM TIGHTLY UP AGAINST THE BUTTON INSULATORS,
CHECK FOR PROPER CENTERING ONE MORE TIME. Proceed by adding the keeper
washers to the rest of the rod directors until all have been center-checked and have the
keepers installed.
