STEP 1: INSTALLING ANCHOR
FOUNDATIONS
Refer to Figure 2-17 and Figure 2-18, DETAIL ‘C’ 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 40 feet from the tower base.
Space the anchor foundations 120 degrees apart.

STEP 2: CONNECTING GUY WIRE
SECTIONS TO THE UPPER MAST
Locate the top load guy wires section ‘B’ (item 3).
Install three eyebolts in the upper mast assembly (see
DETAIL ‘A’), ensuring 120 degrees of spacing
between each eyebolt. Install guy wires through
eyebolts; secure excess wire length from the element
to the upper mast assembly using stainless steel hose
clamp (item 10).
Locate insulator (item 4) and install top load guy wire
in insulator’s eyebolt (see DETAIL ‘B’); secure excess
wire length to the insulator using stainless steel hose
clamps (item 5). Repeat for all three guy wires.
Locate the top load guy wires section ‘A’ (item 2).
Install guy wires through insulator eyebolts (see
DETAIL ‘B’); secure excess wire length from the wire
element to the insulator using stainless steel hose
clamps (item 5). Repeat for all three guy wires.

STEP 3: ERECT ANTENNA
STEP 4: ANCHORING GUY WIRES TO
CONCRETE BASE
Extend the turnbuckle at the end of each top load guy
wire section ‘A’ to its maximum length and secure it to
the associated anchor rod in the anchor foundation
(see DETAIL ‘C’). If you require more guy wire length,
loosen the wire rope clips at the upper end of the
turnbuckle (see DETAIL ‘D’) 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 370 lbs.
Assemble the ground rod and the ground rod
connector (see DETAIL ‘C’) and drive the ground rod
to a depth that leaves only two inches (approximately)
of ground rod exposed above the ground. Connect any
remaining TLE 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.
