STEP 1: INSTALLING ANCHOR
FOUNDATIONS
Refer to Figure 2-17 and Figure 2-19, DETAIL ‘B’ for
anchor foundation specifications.
IMPORTANT
:
Ensure the first anchor foundation is positioned such
that it is in the direction to which the antenna points
when in its horizontal orientation (i.e., before erecting).
Position each anchor so that the anchor rod exits the
ground approximately 7 feet from the tower base.
Space the anchor foundations 120 degrees apart.
STEP 2: CONNECTING GUY WIRE
SECTIONS TO THE LOWER MAST
Locate the guy wire assemblies (item 2). Install three
eyebolts and associated hardware in the lower mast
assembly (see DETAIL ‘A’), ensuring 120 degrees of
spacing between each eyebolt. Secure excess wire
length from the element to the lower mast assembly
using stainless steel hose clamp (item 6). Allow the
guy wires to hang loose until after antenna erection.
NOTE:
Ensure ample clearance between each guy
wire and the ATU output cable.
STEP 3: ERECT ANTENNA
STEP 4: ANCHORING GUY WIRES TO
CONCRETE BASE
Extend the turnbuckle at the end of each guy wire
assembly to its maximum length and secure it to the
associated anchor rod in the anchor foundation (see
DETAIL ‘B’). If you require more guy wire length,
loosen the wire rope clips at the upper end of the
turnbuckle (see DETAIL ‘C’) as required. Once the
wire is linked to the eyebolt, pull excess wire back
through the wire rope clips and tighten clips when rope
is taut. Tighten the turnbuckle to achieve a tension on
each guy wire of 1570 lbs. If you cannot achieve the
required tension, extend the turnbuckle. Loosen the
wire rope clips, increase the tension and then
decrease the turnbuckle length to the desired tension.
Assemble the ground rod and the ground rod
connector (see DETAIL ‘B’) and drive the ground rod
to a depth that leaves only two inches (approximately)
of ground rod exposed above the ground. Connect any
remaining cable to the ground rod connector, after the
wire rope clips, so that the connection is just loose
enough to permit movement. Cut excess cable from
the end of the wire rope.
