Base Bracket Assembly
Select the DX-77-A Base Parts Pack. If you will
be using the tilt-over feature, you will need to drill
a 3/8" hole through your support mast at the
mounting location. To do this easily, first install
two of the base brackets on your support mast and
secure.
Use a 3/8" drill bit to drill through each side of the
mast using the holes in the brackets as guides.
Assemble the mast brackets to both the support
mast and to Tubing Section # 1 Assembly as
shown in Figure 5. (Temporarily remove Tubing
Section #2 and above while assembling the mast
brackets to the mast). Practice swivelling Section #1 to a vertical posi-
tion and installing the other bolts. With help from
at least one more person, reattach the rest of the
antenna, then swivel the DX-77-A to a vertical
position and install all the mounting bolts as
shown in Figure 6. Tighten securely!
NOTE: Tightening the pivot bolt more (Item 14)
will help hold the antenna during raising and low-
ering.
CAUTION:
Do not attempt to raise or lower this antenna by
yourself.
