Rohn 45SR020 45GSR 20 Foot Self Supporting Tower

Compact 20 Foot Self-Supporting Tower for Antenna and Camera Installations
The Rohn 45SR020 is a 20-foot self-supporting tower system designed for mounting antennas, surveillance cameras, and communication hardware where a short, freestanding structure is needed. Constructed with Rohn’s robust 45GSR series steel tower sections, this configuration is engineered to deliver long-term performance in a permanent installation. Ideal for broadcast sites, security monitoring, utility applications, and WISP setups, it offers a balance of low-profile height and high load capacity.

Rated for High Wind Loads With Impressive EPA Support
This tower is built to handle serious environmental demands. It supports up to 95 square feet of antenna load at 90 MPH, 82 square feet at 100 MPH, and 67 square feet at 110 MPH with no ice. These EPA (Effective Projected Area) wind load ratings make the 45SR020 a powerful option for applications that require high equipment loads in moderate to severe wind regions. Whether you're deploying cellular antennas, wide-angle security cameras, or telemetry gear, this tower is up to the task.

Freestanding Tower Design With No Guy Wires Required
The Rohn 45SR020 uses a self-supporting structure that does not require guy wires or large footprint anchor systems. Instead, it relies on a concrete-embedded base foundation using either a 45GSRSB short base section or a partial 10-foot 45GSR section. This makes it especially useful in areas where land usage is limited or ground space is constrained, including rooftops, industrial sites, and municipal installations.

Built With Rugged 45GSR Steel Sections for Long-Term Strength
The tower is constructed from triangular 45GSR tower sections featuring tubular steel legs and all-angle bracing. Each section is hot-dip galvanized for maximum corrosion resistance, ensuring durability over years of outdoor exposure. These sections are industry-trusted for their strength and compatibility with a wide range of antennas, mounts, and tower accessories.

Supports a Wide Range of Communication and Surveillance Equipment
With its high EPA capacity and compact height, the Rohn 45SR020 tower is perfect for equipment like VHF/UHF antennas, PTZ security cameras, point-to-point wireless systems, and sensor arrays. The freestanding design and wind tolerance make it a reliable choice for professionals installing gear in tough environments without the need for large-scale infrastructure.

Includes Structural Components for Secure Foundation-Based Installations
This tower kit provides all the required structural steel components to build a 20-foot freestanding tower. It is intended to be installed with an embedded base per Rohn engineering guidelines. The tower configuration complies with Revision G structural standards and supports safety equipment requirements for structures over 10 feet, such as climber safety devices.

Designed for Code Compliance and Future Flexibility
The modular design allows for height expansion if your site requires additional elevation later. It also meets Revision G compliance, making it suitable for regulated environments and professionally engineered installations. While this kit does not include a lightning rod or beacon plate, these accessories are available for those needing FAA or grounding compliance.
