2. The recommended wind load assumes proper installation, proper anchoring, and total
instrument projected area of less than two square feet. For the RFM18 base, the wind load
recommendation also assumes that the UTGUY turnbuckles are preloaded to equalize
tension, and the tower is guyed at a 60-degree angle relative to the ground (maximum).
The amount of wind load that these towers can withstand is affected by quality of
anchoring and installation, guy wire tension, soil type, guy angle, and the number, type,
and location of instruments fastened to the tower.
3. The UT30 is Universal Towers model #9-30. A more detailed drawing of this tower is
