Self-Supporting 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 weight of the Foundation and the cohesive of the soil to counter a 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), Height, Standard Soil Conditions, Surrounding Environment and Duty. 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 find the Tower Quote Data Sheet Form by clicking the link that appears on the Footer of this Page Below. *Per Rev G requirements, any structure greater than 10' foot requires a climber safety device.

ROHN 55G Guyed Tower with Complete Kits
TIA/EIA-222-G, the national standard´s seventh revision for Steel Antenna Towers and Antenna Supporting Structures, became effective January 1, 2006. REV. F wind loading is calculated according to the Fastest-Mile Wind Speed for the structure´s location as recorded from the 1-in-50-year wind speeds encountered at that location that were constant over a distance of one mile. REV. G requires that wind loading be calculated according to the three-second-gust wind speed, allowing the tower´s design to accommodate instantaneous loads. Loadings will be determined by specific local county criteria from wind, ice, and seismic maps.
Tower and foundation installations should be performed by qualified and experienced personnel using construction drawings. This document is to serve as a guide for sizing and buying the 55G tower. All types of antenna installations should be thoroughly inspected by qualified personnel and re-marked with appropriate danger and anti-climb labels at least twice a year to ensure safety and proper performance.
Wind Loading, Antenna Loading and Wind Survivability ratings vs. Height Documentation Provided by ROHN is available here as a Resource, but is by no means complete by itself or a substitution for Engineering Conducted Specific to your Application. Contact Us with any Questions you may have regarding Use prior to Purchase. All Information regarding the ROHN 55G Tower line, Parts and Accessories is as accurate and complete as we can possibly provide given that this Resource Offering is subject to change without Notice and is beyond Our Control.
DESIGN NOTES:
1. Tower designs are in accordance with ANSI/TIA-222-F-1996 and ANSI/TIA-222-G-2005, Class I Structures.
2. Design assumes towers are installed on level ground. Lower EPA values will apply for roof mounted towers or for sites located on unusual terrain.
3. Designs assume two 7/8" diameter lines on each tower face.
4. Anchor radius is from tower base to intersection of anchor rod with ground.
5. Tower designs and guy chord lengths shown are based on level ground. Initial tensions for guys in pounds at 60º Fahrenheit are shown in ( ).
6. Antenna and mounts are assumed symmetrically placed at the tower top.
PARTS LIST NOTES:
1. Items listed are required for complete (ground) guyed towers. Base and anchor details will be required for installation on roofs or for sites located on unusual terrains and wind loading criteria, for all roof type installations.
2. Standard guys provided with each standard tower include an additional 6% length.
3. Anchor grounding (AGK1GGX) and base grounding (BGK3GGX) are included with the tower material.
4. Installation information and a safety package (P/N: ACWS) are included with each tower.

GUIDELINES FOR THE PREPARATION OF A GEOTECHNICAL REPORT
I. PURPOSE AND INTENT
a) The intended purpose of these guidelines is to assist the customer and/or owner to retain the services of a Geotechnical Engineer.
b) It is not ROHN´s purpose or intent to supersede the Geotechnical Engineer´s knowledge, judgement and/or experience. It is the Geotechnical Engineer´s responsibility to add or delete from these items, based on local site conditions and other factors.
c) Additional information is provided in ANSI/TIA-222-G Annex G "Geotechnical Investigations".
II. DISCLAIMER
a) ROHN will not accept any liability, either expressed or implied, for the use of, and omissions in, these guidelines.
III. EXPLORATORY BORINGS
a) Borings should be taken at tower legs for self-supporting towers and at the base and anchor points for guyed towers. For small self-supporting towers, two borings may suffice. For large self-supporting towers, one boring should be taken at each tower leg. A "small" self-supporting tower is assumed to have a face width less than 20 feet and a compression load less than 50 kips per leg. For pole structures, one boring may suffice.
b) The minimum boring depth should be 30 feet for pole structures, self-supporting towers and guyed tower bases. For guyed tower anchors, the minimum depth should be 15 feet. The actual depth of boring must be determined by the Geotechnical Engineer based on reactions, soil conditions and the type of foundation recommended.
c) If borings cannot be advanced to the desired depth, rock core samples should be taken. Rock Quality Designation (RQD) values and compressive strengths should be determined.
IV. GEOTECHNICAL REPORT
a) The following properties, for each soil layer encountered, should be determined by field or laboratory testing and summarized in the geotechnical report:
1. Soil classification and elevations
2. Standard penetration values
3. Unconfined compression strength
4. Angle of internal friction
5. Cohesion
6. "In-Situ" soil density and moisture content
7. Rock quality designation (RQD) and percent rock sample recovered
8. Other properties unique to site conditions
b) The following items should be discussed in the geotechnical report:
1. Geological description of site
2. Observed and expected ground water conditions
3. Expected frost penetration depth
4. Corrosion potential of soil and corrosion protection recommendations
5. Site access and potential construction difficulties
6. Dewatering or site drainage requirements
7. Backfill material recommendations
8. Settlement considerations
9. Additional information to aid foundation designer
10. Recommended types of foundations
11. Design parameters for uplift, download and lateral load
12. Factor of safety considered when allowable vs. ultimate design parameters are provided
13. Recommended construction techniques and inspections
