VEC-896 Vertical Antenna Instructions

9. Slide the bottom radiator (the one with two sets of holes) over the fiberglass rod with the
holes that are 2" from the end toward the base mounting bracket. Slide a hose clamp to the
bottom of the element. The radiator should butt against the insulating plastic of the base
mounting bracket. Install a 1/4 x 7/16" bolt through the element and fiberglass rod and
tighten with a lock washer and 1/4 x 7/16" nut.
10. Slide three more hose clamps over the bottom element. Tighten the hose clamp installed
in step 9 over the slit in the bottom element. This clamp will make the antenna more rigid.
11. Insert the fiberglass center insulator into the bottom element and insert a 1/4" x 7/16" head
bolt with a lock washer through the hole. Thread a 1/4" x 7/16" nut on the other end.
Finger tighten only. See Figure 3. Slide a hose clamp over the center insulator. Tighten
the hose clamp on the slit in the bottom element. Slide another hose clamp over the
insulator.
12. Slide the top 1 1/8" diameter element over the center insulator and install the 1/4" x 7/16"
head bolt and nut as in step 10. Tighten the hose clamp over the slit in the top element
until the element will not sway.
13. Slide three hose clamps over the top element.
Note: The upper and lower stubs (U-channel "L" brackets) on each band should not be installed
perfectly in line. There should be enough offset so that the threaded ends won't touch if
the stubs are fully shortened. The alignment of the stubs will not affect operation. See
Figure 5.
