Guyed Towers are limited in Height due to the nature of Antenna and Ice loads versus the Cantilever Nature Of Wind against them, offset by the Downward force of all Downguy tensioned as specified, terminated to a properly embedded Anchor, the weight/size of the Foundation and the cohesive of the soil to prevent skid/pullout and all together to counter a Structural Failure or Tower tip-over moment, as well as the strength of the tower members to withstand these Forces against them. ROHN Tower Kits are designed based on assumptions made regarding Windspeed, EPA (Antenna Load), Ice Load, Transmission Cable Loads, Height, Standard Soil Conditions, Surrounding Environment and Duty (Exposure Categories).
The Pre-packaged Kits contain the parts called for based on this Stock Design. The Stock Design of these Kits does not account for the Variations of Historic Windspeed, Number of Antenna(e) Loading at Specific Height(s), Soil Engineering recommendations, Adjacent Structures, Communications Purpose, or Geo-Political Rules, Laws and Codes That will be Applicable to Your Project.
It is Recommended that you take the time to engage an local Engineer that has the expertise and available Information necessary to evaluate the Stock design for Applicability, and/or Fill Out the Tower Quote Data Sheet Form found by clicking the Specification Tab above and send to 3 Star Inc./ROHN for a review.
*Per Rev G requirements, any structure greater than 10' foot requires a climber safety device.

TURNBUCKLES / CLEVICES / STRANDVICE
Hot Dipped Galvanized is used to adjust the tension on Guyed Towers
GUY WIRE
3 Star stocks guy wire for use in guying antenna masts and ROHN 25G, 45G, 55G and 65G towers. Choose from 6/18 and 6/20 for telescopic antenna masts and 1/4 inch to 5/16 inch EHS strand for guying down ROHN Towers. Our 6/18 and 6/20 guy wire comes in lengths of 50' , 100' , 250 ,500, to 1000' FT and our EHS Tower Guy wire comes in 100' , 250' , 500' ,1000, in coils / reels and 5000' FT wooden spools. PLP-GWD Guy wire Dispenser available (optional)
Complete Telescopic Guy Wire Kits are also available.
ANCHORS
Guy Anchors are used to attach the guy-wire that helps support a tower, antenna mast or even utility poles. The anchoring is accomplished by using rods, usually made from galvanized steel, that are screw driven, concreted into the ground or backfilled with earth.
An anchor must be designed and rated to resist the maximum amount of tensile load, forces tending to cause extension of the guy wires and anchoring system; both the dead load of the tension of the wire and the maximum possible theroretical live load due to wind, gravity, ice and other forces of nature. The attached guy wires exercises its force at an angle, and because of this angle the anchor will have r two forces of both, vertical or (up and down) and lateral (back and forth) forces on it known as lateral shear. Ground anchors rely on the lateral shear strength of the soil. This strength or cohesion helps to mitigate by spreading the the forces from the guys wires connected to it over a large surface area.
