(Item. No. 5).
Slip both radial assemblies over the top of the
48" tube and position as shown in Figure 4 and

For example, at 221 MHz, B= 16 1/2" (419 mm).
Tighten all screws in both radial assemblies
securely and evenly.
Select the mast-to-mast clamps and associated
hardware and loosely assemble them as shown in

bottom end of the 48" tube as shown in Figure 2
and securely tighten the four (4) 1/4"-20 x 3/4"
