g.
Using the same guy rope as a radius guide, walk across to the approximate location of the second
ground anchor. Establish the required 120
o
from the first ground anchor by using the triangular shape
of the base plate as a reference. Drive in a second ground anchor at this point.

h.
Repeat step g for the third ground anchor.
i.
Disconnect the guy rope used for a radius marker. Attach the fixed (upper) snap hook to the attachment
point on the antenna adapter. Attach the running hook at the lower end to ground anchor 2. Note that
the winder remains attached to the lower ends of the guy rope to prevent accidental loss.
j.
Take a second guy rope. Attach the fixed (upper) snap hook to the antenna adapter attachment point.
Attach the running hook at the lower end to ground anchor 3.
k.
Attach the upper snap hook of the third guy rope to the adapter attachment point. Unwind the rope
along the length of the mast toward the ground anchor 1, but do not attempt to attach the lower end yet.
Ensure that guy ropes will not snag coaxial cable when mast is raised.
