Rohn RSL20H90 RSL Self-Supporting Towers

Compact Tower Package for Secure Communications Support
The Rohn RSL20H90 is a 20-foot self-supporting tower kit made up of heavy-duty sections 9 and 10 of the RSL series. Designed for performance in demanding communication environments, this modular tower segment is ideal for applications such as two-way radio, broadband distribution, public safety infrastructure, and security systems. It provides reliable structural support for mounting antennas above common obstructions like treetops and buildings.

Optimized for Rooftop and Ground Installations
Whether used on a rooftop or a ground-based foundation, this tower system delivers flexibility and strength. The lap splice leg connection system simplifies alignment, while consistent brace lengths and bolt sizing ensure a faster, more intuitive installation. Its modular nature means it can be integrated with other RSL components or function as a standalone structure in compact vertical applications.

Engineered for Demanding Site Conditions
This tower kit is engineered to accommodate common loading requirements in both urban and rural deployment environments. Sections 9 and 10 are fabricated for durability under wind loads and can support antennas for public works, private enterprise systems, and point-to-point communication networks. Expansion options like accessory shelves, grounding kits, and step bolts allow for system customization as site demands evolve.

Hot-Dip Galvanized for Long-Term Protection
To extend its service life, the RSL20H90 tower is hot-dip galvanized after fabrication. This finish provides excellent corrosion resistance in environments where moisture, salt, or temperature swings could compromise steel integrity. It's a critical factor for users operating in coastal regions, storm-prone zones, or high-humidity climates.

Meets Modern Safety and Mounting Requirements
The tower includes pre-punched holes that support attachment of safety climb systems, mounting kits, and accessory components, making it suitable for installations requiring compliance with safety and building codes. Additional safety options—such as anti-climb panels and lightning rods—are available for installations where public or occupational safety is a concern.

Expandable with Optional Accessories
The Rohn RSL system is designed for flexibility, and the RSL20H90 tower is no exception. Optional components like top posts, grounding kits, waveguide brackets, and climbing hardware can be added to meet specific communication system needs. With support for standard hardware and a consistent assembly design, this tower integrates easily into both new builds and upgrade projects.
