Rohn 55G90R120 55G Complete Tower Kit

120-Foot Guyed Tower System for Heavy-Duty Antenna Installations
The Rohn 55G90R120 is a complete 120-foot guyed tower kit engineered for high-performance communication applications. Designed as part of the Rohn 55G heavy-duty series, this tower supports antenna configurations up to 37 square feet in surface area while withstanding wind gusts of up to 90 mph (3-second gusts, no ice). Ideal for commercial broadcasters, public safety communication networks, and multi-antenna systems, this tower combines impressive strength, structural integrity, and adaptability in one dependable system.

Heavy-Duty Tubular Steel Frame with Solid Bracing
Built with oversized tubular steel legs and solid round rod cross members, the 55G90R120 tower provides unmatched strength and wind resistance. The zig-zag bracing layout between tower legs reinforces each 10-foot section and enhances torsional rigidity. This design helps maintain alignment under load, prevents excessive movement, and ensures long-term reliability in demanding environments.

Supports Large Antenna Loads in Challenging Conditions
With a load rating of 37 square feet at 90 mph wind gusts, this tower is capable of holding multiple antennas or heavy-duty broadcast arrays. Whether supporting high-gain directional antennas, microwave dishes, or FM broadcast equipment, the 55G90R120 provides the height and load capacity required for professional-level installations. The 120-foot height is particularly useful for increasing transmission range and signal clarity in expansive or elevated terrain.

Versatile Base Options Match Varying Site Needs
Installers can choose from multiple base configurations to match project-specific requirements. Options include a standard anchor bolt base plate, a hinged base for ease of erection and maintenance, or a concrete-embedded base for permanent anchoring. These choices allow the tower to be adapted to different soil types, terrain conditions, and site accessibility constraints.

Double-Bolt Section Connections for Reinforced Stability
Each 10-foot modular section of the 55G tower uses a double-bolt joint system for stronger, more secure connections. These joints distribute structural stress more evenly and prevent long-term wear or joint slippage under wind loading. This feature significantly increases the tower’s resilience, making it well-suited for tall towers supporting large antennas over long-term deployments.

Corrosion-Resistant Finish with Hot-Dip Galvanization
To ensure durability in outdoor and high-moisture environments, all tower components are hot-dip galvanized after fabrication. This protective zinc coating shields every weld and surface from corrosion, making the tower suitable for coastal regions, high humidity zones, or locations exposed to seasonal freeze-thaw cycles. Minimal maintenance is required, even over extended years of service.

Ideal for Broadcast, Wireless, and Emergency Infrastructure
The 55G90R120 tower is a go-to solution for organizations needing long-term communication support with high structural demands. It is commonly used in FM and UHF broadcasting, two-way radio networks, telemetry systems, public safety communications, and rural wireless ISPs. With industry-standard compatibility, heavy-duty build quality, and reliable height performance, it’s a trusted tool for critical communication infrastructure.
