Rohn 45GSR90R140 140FT Guyed Tower

140-Foot Guyed Tower Built for Strong Wind Zones and High Load Requirements
The ROHN 45GSR90R140 is a 140-foot complete guyed tower system engineered for heavy-duty communication, surveillance, and broadcast installations. Rated for 90 MPH 3-second gusts and capable of supporting up to 63.5 square feet of antenna surface area, this tower is ideal for users who need extended range, signal clarity, and reliable performance in a compact footprint. Whether you're building out a rural broadband network, expanding a public safety system, or supporting broadcast infrastructure, this tower delivers dependable structural support.

Solid Round Steel Legs Provide a Heavy-Duty Structural Core
This tower features solid 1.25-inch round steel legs, delivering superior vertical load capacity and structural resilience. Unlike hollow-leg towers, the solid-rod design ensures consistent strength under compression, wind stress, and equipment weight. These legs form the backbone of the tower, ensuring long-term durability for high-performance antenna systems in demanding outdoor environments.

Zig-Zag Bracing Enhances Stability and Wind Load Handling
The 18-inch triangular face design is reinforced with continuous solid-rod zig-zag bracing, enhancing torsional rigidity and resistance to lateral movement. This bracing system helps distribute structural loads more evenly, keeping antennas properly aligned and reducing sway under wind pressure. The result is better performance, lower maintenance, and increased confidence in system uptime during inclement weather.

Modular Sections with Double-Bolted Joints for Easy Assembly
The 45GSR90R140 is constructed from 10-foot modular sections that connect using double-bolted joints. This design improves section-to-section stability and reduces vibration-related wear. The modular approach simplifies transportation, staging, and field assembly, which is particularly beneficial for tower crews working in remote or constrained environments.

Hot-Dip Galvanized Finish Protects Against Rust and Corrosion
All components are hot-dip galvanized after fabrication, ensuring each part has complete coverage with corrosion-resistant coating. This protective layer enhances the tower’s lifespan, especially in environments exposed to moisture, salt air, or industrial pollutants. It also reduces long-term maintenance demands, keeping the tower structurally sound for years to come.

Multiple Foundation Options Allow Flexible Installation
The tower can be installed using a variety of base configurations to match the specific needs of your site. Choose from a base plate with anchor bolts, a hinged base for tilt-up installation, or a cast-in-place concrete base. This flexibility allows the 45GSR90R140 to adapt to a wide range of terrains, soil conditions, and project constraints without compromising structural integrity.

Optimized for Wireless, Broadcast, and Surveillance Applications
Designed for high-performance utility, this 140-foot tower supports a wide variety of antennas used in wireless ISP deployments, FM transmission, security monitoring systems, and more. It strikes a balance between height and structural capability, offering a scalable solution for mission-critical infrastructure with high wind loading demands.
