Rohn RSL20H12 Self-Supporting Towers

Built for Height, Strength, and Versatility
The Rohn RSL20H12 is a 20-foot, heavy-duty self-supporting tower system engineered for professional and recreational users who demand dependable structure and simplified installation. Designed for applications such as amateur radio, broadband distribution, security systems, and public safety networks, this two-section tower provides a rugged platform that reaches above treetops, rooftops, and terrain challenges without the need for guy wires or additional bracing.

Engineered for Easy Transport and Assembly
This tower ships knocked down to reduce shipping costs and simplify logistics. Each section is crafted with identical-length braces and standardized bolts, which significantly streamline assembly time and reduce hardware confusion in the field. The RSL system is known for its clean lap splice connection, made possible by U-shaped leg profiles that align and secure with ease.

Hot-Dip Galvanized for Long-Term Durability
Constructed from corrosion-resistant steel that has been hot-dip galvanized, the RSL20H12 is built to endure extreme environmental conditions, including prolonged exposure to rain, snow, and sun. This ensures reliable structural integrity and minimal maintenance over time, making it a practical solution for long-term permanent tower installations.

Customizable with a Full Range of Mounting and Safety Accessories
Rohn offers a full suite of optional accessories that can be paired with this 20-foot tower for additional functionality and code compliance. These include top posts, safety climbing systems, grounding kits, anti-climb devices, and step bolts. Pre-punched mounting holes on the tower make it easy to attach these items without additional modification or drilling.

Ideal for Amateur Radio, Surveillance, and Wireless Communications
Whether you're setting up a repeater, a security camera, or a broadband relay, the RSL20H12 provides the stable height advantage necessary for signal clarity and coverage. Its compact 20-foot design makes it ideal for residential or smaller-scale deployments, while maintaining the same structural consistency found across the RSL series from 20 ft. up to 100 ft.

Standardized Section Design Simplifies Expansion
All RSL tower sections use consistent bolt lengths and brace dimensions, allowing future height upgrades or structural enhancements without the need to reconfigure your base hardware. This uniformity also helps reduce spare parts inventory for larger installations or maintenance programs.

Reliable Documentation and Structural Support
Every Rohn RSL tower includes detailed assembly drawings to guide the installation process, supporting both professional contractors and DIY users. The top angle closure is included as standard, rounding out a complete tower package ready to integrate with your communications, surveillance, or broadcasting equipment.
