Rohn 45GSR90R100 100FT Guyed Tower

100-Foot Guyed Tower Engineered for 90 MPH Wind Zones
The ROHN 45GSR90R100 is a 100-foot complete guyed tower system designed for communication and broadcasting projects that require solid structural performance in wind-rated environments. With a 90 MPH 3-second gust rating and the capacity to support up to 78 square feet of antenna surface area, this tower is ideal for broadband delivery, public safety systems, amateur radio, and long-range surveillance. Its high-strength build and reliable design make it a trusted solution for permanent outdoor installations.

Solid Steel Legs Provide Exceptional Vertical Support
The tower is built with solid 1.25-inch round steel legs, delivering robust compressive strength and stability for mounted antennas and equipment. These legs are engineered to handle significant weight and environmental stress, making the tower dependable under continuous operation. Unlike tubular alternatives, solid steel legs ensure structural integrity over time, especially in installations exposed to wind or variable loading.

Triangular Face with Zig-Zag Bracing Improves Rigidity
With an 18-inch triangular face and continuous zig-zag bracing across all sides, this tower offers improved torsional resistance and reduced sway. The solid rod bracing efficiently distributes both mechanical and environmental loads, ensuring steady performance even during sudden wind shifts. This geometry helps maintain antenna alignment, critical for maintaining signal reliability across wide service areas.

Modular 10-Foot Sections for Easy Transport and Setup
The 45GSR90R100 tower is assembled using modular 10-foot sections that feature double-bolted joints at each connection point. These reinforced joints increase stability across the entire structure while simplifying field assembly. The modular format makes it easier to transport, stage, and install—especially beneficial for remote or challenging job sites.

Hot-Dip Galvanized Finish Extends Service Life
All tower components are hot-dip galvanized after fabrication, providing full protection against rust, corrosion, and long-term weather exposure. This coating is essential for outdoor towers, particularly in humid, salty, or snowy climates where unprotected steel would degrade over time. The result is reduced maintenance needs and years of reliable structural performance.

Flexible Foundation Options for Site Adaptability
The ROHN 45GSR90R100 can be anchored using three different foundation options: a base plate with anchor bolts, a hinged base for tilt-up construction, or a direct-embed base cast into concrete. These configurations provide versatility across a wide range of installation environments, helping engineers tailor the foundation to the unique conditions of each job site.

Optimized for Communication, Surveillance, and Data Networks
With 100 feet of height and a high antenna load rating, this tower is well suited for supporting broadband antennas, FM repeaters, IP surveillance gear, and more. Whether serving as a central hub for rural internet or an extension for a growing communication system, the 45GSR90R100 delivers the strength and performance needed for demanding applications.
