    ROHN 25G Bracketed Tower

    The 25G Bracketed Tower can be installed adjacent to buildings using a bracket to secure the tower in one or two locations along the height of the structure.

    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 susbstitution 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 25G 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.


    ROHN 25G Bracketed Tower

    DESIGN NOTES:
    1.
    Tower designs are in accordance with approved national standard ANSI/EIA-222-F.
    2. All towers must have "fixed" bases. Pinned bases may not be used.
    3. Designs assume transmission lines symmetrically placed as follows:
    25G Tower - One 5/8" Line on each face ( Total =3)
    4. Antennas and mounts assumed symmetrically placed at tower apex.
    5. Allowable antenna areas assume all round antenna members.
    6. Allowable flat-plate antenna areas, based on EIA RS-222-C, may be obtained by multiplying areas shown by 0.6.
    7. All brackets are to be ROHN (P/N HBUTVRO)
    8. The interface of tower brackets to supporting structure is to be designed by others and must support a minimum horizontal force of 815 lbs.

    FEATURES:
    o
    Completely hot-dip galvanized after fabrication to provide absolute corrosion protection.
    o Cross bracing is formed by a continuous solid rod bracing in a zig-zag pattern for strength.
    o Pre-engineered loading charts meet varying individual specs and site conditions.
    o Typical uses include small dishes, broadband, security and two-way communication.

    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 supercede 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 corings 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
