Assembl y
Select the boom support tubes (Items 24, 27, 28),
U-bolt (Item 48), U-bracket clamp (Item 38),
boom support straps (Item 36) and associated
hardware as shown in Figure 7.
Attach the boom supports to the 1 1/8 inch boom
sections as shown in Figure 7. The boom supports
can be above the boom tube or below the boom,
when installed. Tighten the # 10 hardware
Install the assembled antenna with boom support
on a temporary mast at eye-level, so that the
boom support tubes may be adjusted to level the
boom. The dimensions shown in Figure 7 are
close, however some adjustments may be
necessary.
Disassemble the U-bolt and U-bracket clamp and
tape the boom support tubes to the boom until
installation on your mast or tower
NOTE: The 215DX antenna assembled per
these instructions should be balanced with
respect to wind load. If you wish to balance
this antenna with respect to weight, the boom-
to-mast bracket and U-bracket clamp may be
moved closer to the D7 element. If used in a
phased array, all antennas should be
assembled identically.
