1. Begin by installing element #11, the smallest element. Locate the bag of twenty (20) HD CRA-
DLES with 7/8” radius to fit the 7/8” fiberglass rods. These cradles have clearance holes for 5/16”
diameter bolts. Drop four (4) 5/16-24 x 4” bolts down through the element #11 mounting plate.
Hold the center of element #11 up near the plate and place two saddles on the center of 7/8” fi-
berglass rod. Raise the element up and feed the bolts down through the cradles. Place another
cradle under each upper cradle and add locknuts. Tighten up the nuts until the element is almost
secure. Then center the element through the cradles and rotate the element until the bolts at the
element butt are up and their corresponding nuts are down. Tighten the cradle bolts evenly and
completely. Now orient the PHASE LINE CLAMP ASSEMBLIES on the element butts so the
PHASING LINE CLAMP CAP are DOWN and square with the boom.
2. Continue mounting element #10, #9, #8, and #7 in order as described above.
3. Element #6 is different only as it has a 1” fiberglass rod and (4) HD CRADLES with 1” radius, fit-
ting the fiberglasss rod perfectly. Use (4) 5/16-24 x 4” bolts and locknuts to secure the element.
4. Element #5 and #4 both use 1-1/4” fiberglass rods and (4) HD CRADLES with 1-1/4” radius.
Use 5/16-24 x 4-1/2” bolts and locknuts.
5. Because of their size and weight we have suggested that just the INNER SECTIONS of element
#3, #2, and #1 be mounted before the whole element is assembled. Element #3 and #2 use 2”
fiberglass rods and (4) HD CRADLE with 2” radius. These cradles require 3/8-24 x 5” bolts and
locknuts. Before tightening cradles completely be sure to rotate the element so the 3/8” PHASE
LINE CLAMP CAPS are down and their bolts are perfectly perpendicular with the TOWER
BOOM legs. Doing this will facilitate the installation of the phasing lines in the subsequent as-
sembly steps.
6. Element #1 uses a 2” fiberglass rod and (8) HD CRADLES with 2” radius. These cradles require
(8) 3/8-24 x 5” bolts and locknuts. Again center and rotate the element in the cradles so the 3/8”
PHASE LINE CLAMP CAPS are down and their bolts perpendicular to the TOWER BOOM legs.
7.
OPTIONAL
: THE TIP SECTION OF ELEMENTS #3, #2, AND #1 CAN NOW BE INSTALLED.
You may also elect to do the element tip installation just prior to the antenna being place on a
tower. If you do it now or later, refer again to the appropriate element assembly sheet for the
hardware required to attach the tip sections.
8. Now do the final check and tightening of the all elements forward to the Element #11. TIGHTEN
each bottom cradle EVENLY AND SECURELY.
