Rohn 45GSR130R090 45G Complete Tower

Reliable Wind-Rated Tower for Light-Duty Applications
The Rohn 45GSR130R090 Complete Tower is a 90-foot guyed structure designed for dependable performance in windy conditions, rated for up to 130 MPH 3-second gusts. Whether you're deploying antennas for amateur radio, broadband, public safety, or commercial use, this tower offers a sturdy, lightweight support system with a small footprint and excellent wind load handling. With a 12.1 square foot antenna surface load capacity, it provides a flexible foundation for a wide range of RF systems.

Modular 10-Foot Sections for Flexible Builds
This tower system is built from modular 10-foot sections, making transportation and installation straightforward. Its stackable design allows for easy scaling to meet height requirements while maintaining consistent strength throughout the tower’s vertical span. Whether you’re planning a permanent installation or anticipating future extensions, the 45GSR format ensures adaptability at every level.

Solid Steel Construction with Enhanced Joint Integrity
Engineered with solid round steel legs, the 45GSR130R090 tower ensures higher structural strength than tubular-leg designs. The sections connect using 4-bolt flanged joints, providing improved rigidity and torque resistance, particularly important for windy sites or applications involving directional antennas. Each tower segment is double-bolted and secured with high-tensile fasteners for long-term security and minimal maintenance.

Zigzag Bracing Improves Wind Load Distribution
To ensure uniform stress distribution, this tower uses continuous solid-rod bracing in a zigzag formation. This design improves the tower’s ability to absorb dynamic wind forces while reducing torsional sway, even under load. Combined with guyed support systems and correctly installed anchors, the 90-foot Rohn 45GSR maintains its shape and function reliably across changing weather conditions.

Hot-Dip Galvanized for Long-Term Durability
All tower components undergo a hot-dip galvanizing process after fabrication, sealing all surfaces with a corrosion-resistant finish. This makes the tower suitable for deployment in coastal areas, industrial sites, or regions prone to heavy precipitation and temperature fluctuations. The galvanization ensures your investment holds up through years of exposure with minimal upkeep.

Customizable Base Options for Installation Flexibility
The 45GSR130R090 supports several base configurations, including base plates with anchor bolts, hinged tilt bases, and direct concrete embeds. This allows the tower to adapt to diverse site requirements and soil conditions, offering both fixed and tilt-up installation flexibility. Grounding kits and guy hardware can be added to complete a full TIA-compliant tower solution.
