Figures 5, 5A, 5B, and 5C show the steps for element assembly.
Identify the tubing sections required for each element using the Element
Subassembly Parts List. Each telescoping tubing section is inserted 4
inches into the larger section except where noted in Figure 5. Adjust the
length of the end tubing section to give each element the proper total half
length. All dimensions should be within 1/4 inch of the values given. Mark
the center of tubing sections EA, EG, and EP with a marker as shown in
Figure 6A. These marks will be used in Step 4 when elements are
mounted on the boom. The dimension between traps TB and T2 is measured
between the ends of each trap. The 75 inch dimension from element #7
center is measured to the end of trap T2. The dimension between traps
T4 and TD is measured between the ends of each trap. The 72-1/2”
dimension from element #9 center is measured to the end of trap TD.
Insure all traps are installed with arrows pointing toward the boom. Also
position trap drain holes so they will be facing the ground when the antenna
is in its final position.
Install all worm clamps as shown. Take care not to overtighten and
strip the worm clamp. Apply electrical tape over the worm clamp and
tubing. This will keep the worm clamps from snagging wires or ropes in
the future. Extra worm clamps are provided. Note that all element sections
can be fastened using a self-taping screw at each tubing transition. Use
stainless screws for best performance. Properly installed worm clamps
will provide years of trouble free service.
The X9 is constructed entirely with .058-inch wall tubing. This creates
a tight transition between tubing sections with the closest possible fit and
better ice-loading characteristics than antennas constructed with thinner
wall tubing. Elements 3, 4, 5 and 6 have fiberglass center sections.
Reference figures 5A, 5B and5C for proper assembly.
After mounting element end caps (53, 77) punch a small hole (1/4”)
in the bottom edge (ground facing side) of each cap for water drainage.
Unless indicated otherwise, telescope
elements 4” (10.16 cm) and tighten
the worm clamp.
