Tower Base Installation - Hy-Gain AV-18HT Instruction Manual

Pour a standard mix of concrete (five parts
sand, one part cement) into the hole until it
reaches ground level. Vibrate the concrete
during the pouring to eliminate voids.
NOTE: For extra security, steel reinforcing
rods can be added to the base before the
concrete is poured.
Insert the base assembly, with legs attached,
into the concrete base until approximately six
inches remain above the concrete, as shown in
Figure 3. Position the assembly so that the
tower can hinge on base assembly "A".
The base assembly must be assembled
level so that the tower will be vertical
when it is installed. Support the base
assembly above the concrete in the manner
shown in Figure 3 while the concrete is
curing.
An easy method to ensure a level base
involves using a low-cost string level.
Loop a length of string through the three
(3) holes on the standoffs above the two
(2) base assemblies. Apply tension until
taut, then tie it off. Hook the string level
onto each part of the string and adjust the
tower base so that each string is level.
