ROHN 55SS060 Complete 60 Foot Self Supporting Tower
This Product Order Supplies the Following BOM (Less Foundation and Installation) in accordance for Use as a Self Supporting 60 Foot ROHN 55G Tower with EPA's (Effective Projected Area) Ratings for 70, 80 or 90 MPH (No Ice). Refer to Brochure on the MORE INFO section of this page for Ice Loading and EPA Information..
Kit Includes :
(2) BGK2G optional
This 55G Tower is to be used in a Self-Supporting Configuration according to Use and Foundation Specifications in the ROHN Catalog. This Height Configuration relies on a R-SB55G Embedded in a Concrete Foundation Specified by Engineering. As a Free-Standing, Self-Supporting Structure, a 70 MPH rated 55G Tower can rise to a maximum of 60 feet. Refer to ROHN 55G Specification Sheet for more ROHN 55G Tower Configuration, Foundation and Grounding Detail Information.
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)
45G Tower - One 7/8" Line on each face ( Total = 3 @ 7/8" & 3 @ 1/2")
55G & 65G Towers - Two 7/8" Lines on each face ( Total =6)
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. Standard foundation designs are based on Rev. F normal soil and Rev. G presumptive clay soil parameters. .
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.
