1.6 Ground Anchor Layout (for Optional Guying Kit)
If you are using the optional guying kit, you will need to consider the overall site
layout both for the tower position and the siting of the guy anchors as detailed
below.
To lay out the base installation with optional guy anchors you will need:
A 15 metre tape measure
Four stakes
6 metres of non-stretch line
Figure 1-5 shows the layout of the guy anchors in relationship to the tower base.
To mark the positions of the guy anchors:
1. Drive a stake into the ground where the tower is to be located.
2. Attach a line to the stake and scribe a circle with a 3.6 metre radius (for
UT20) or a 5.2 metre radius (for UT30).
3. Choose a tilt direction for the tower.
4. From the centre point, walk in the opposite direction and drive a stake into the
ground on the scribed line (see Figure 1-5). This marks the position of the rear
leg anchor.
5. Locate the other anchor points by measuring 6.2 metres (UT20) or 9 metres
(UT30) from the rear tower leg anchor stake to the scribed line.
