Rohn 45GSR90R120 G-Series Guyed Tower

120-Foot ROHN Guyed Tower System Built for Strength and Value
The ROHN 45GSR90R120 is a complete 120-foot guyed tower package designed to get your antennas in the air quickly and securely. Ideal for commercial and public communication systems, amateur radio, microwave, and broadband deployments, this package includes all the major components needed for a solid tower build—minus the concrete and safety gear. With a wind rating of 90 MPH (3-second gusts) and a heavy-duty build, it provides excellent antenna support with pre-engineered reliability.

Engineered with Solid-Rod Steel Legs for Heavy-Duty Support
This 45GSR model features solid round steel legs, delivering superior compression strength and mechanical durability compared to hollow leg towers. The solid-rod leg construction makes this tower capable of supporting larger antennas and withstands heavier loading in environments exposed to wind and vibration. It’s a trusted choice for professionals needing a robust support structure that will hold up over time.

Zig-Zag Solid Rod Bracing for Structural Stability
Each section features continuous solid-rod bracing configured in a zig-zag pattern across the triangular 18" face. This bracing layout reinforces the tower against lateral movement and torsional stress, keeping the tower stable even during high-wind events. The zig-zag bracing also helps distribute load more evenly across the structure, reducing wear on connection points and ensuring long-term reliability.

Modular Tower Sections with Pre-Engineered Components
The ROHN 45GSR90R120 tower consists of 10-foot modular sections that bolt together using double-bolted joints. This modular system not only simplifies transport and staging but also streamlines on-site assembly. Included in the package are all the major tower components such as guy wire, guy brackets, turnbuckles, guy anchor rods, grounding kits, and base anchoring hardware. Everything is designed to meet TIA Revision "F" standards for structural integrity.

Fully Galvanized After Fabrication for Weather Resistance
Every component in the ROHN 45GSR90R120 package is hot-dip galvanized after fabrication, creating a corrosion-resistant coating that’s built to last. This finish protects the tower in harsh outdoor environments including coastal zones, wet climates, and snow-prone areas. With this level of finish, maintenance demands are reduced and tower life is significantly extended.

Flexible for Multiple Antenna Applications
The ROHN G-Series guyed tower systems are widely used in applications ranging from amateur radio to microwave communications, public safety systems, and FM broadcast. With the included hardware and structural layout, the 45GSR90R120 is ideal for projects requiring long-range transmission, reliable data links, and high wind-load capacity.

Installation Requires Certified Personnel and Proper Safety Practices
While this is a complete tower package, it does not include concrete, safety gear, or lifting fixtures. Installation must be handled by trained professionals following national and local codes. Proper grounding, alignment, and tensioning are essential for safe and effective performance. Always use recommended personal protective equipment during erection and servicing.
