NOTE:
When using the RFM18, the user-supplied mounting hardware must be capable of
withstanding the Maximum Wind Load given in
Specifications (p. 8). See Note 2 in that
section for a description of factors that affect wind load. In addition, the tower must make
use of guy wires to further increase the stability of the tower.

7.1.3 Guy anchor installation
There are two types of anchors for the tower guy wires: the UTEYE eye bolts are poured in
concrete; the UTDUK duckbill anchors are driven into the soil.
7.1.3.1 UTEYE eyebolt guy anchor
1. Dig a hole 24 inches square by 24 inches deep at each anchor location ( Base and Guy
Anchor Layout (p. 10)).
2. Optional — Construct a concrete form out of 2-inch x 4-inch lumber, 24 inches square
(inside dimensions) for each hole. Center the forms over the holes and level them by using
a carpenter’s level and stakes.
3. Fill the holes with concrete and install the eyebolts as shown in FIGURE 7-13 (p. 22).
