Assembly
Slide the assembled mast-to-mast clamp over
the bottom end of the 28" tube as shown in
Figure 2 and securely tighten the four (4) 1/4"-
20 x 3/4" bolts, nuts and lockwashers (Item
No.s 18,
20, &
21).
Slip both
radial assemblies over the bottom of
the 28 inch tube and position as shown in
Figure 3. The unslotted end of the 28 inch tube
is the bottom. Determine the "B" dimension
from Figure 6. For example, at 445 MHz, B = 6
3/8" (162 mm)
.
Determine the "C" dimension
from Figure 7. At 445 MHz, C = 2 1/4" (57
mm). Tighten all bolts in both radial assemblies
securely and evenly.
Select the mast-to-mast clamp, plate, and
associated hardware and loosely assemble
them as shown in Figure 2.
