Rohn RSL70H39 RSL Self-Supporting Towers

70-Foot Self-Supporting Tower for Communication, Broadcast, and Security Systems
The Rohn RSL70H39 is a 70-foot self-supporting communications tower built with heavy-duty structural integrity for serious broadcast, public safety, security, and broadband applications. This model uses Sections 3 through 9 of the RSL system to provide a modular, scalable, and strong solution for mounting antennas and communication gear in high-demand outdoor environments. Whether you're building an amateur radio setup or deploying wireless broadband in a rural zone, this tower is engineered to help you get above the noise—literally.

High-Performance Tower That Clears Line-of-Sight Obstacles
Standing 70 feet tall, the RSL70H39 tower reaches above common obstructions like buildings, trees, or hills that interfere with signal transmission. It's an ideal solution for areas requiring clear RF paths for optimal reception and broadcast. The height and structural integrity make this tower a reliable platform for long-range data links, two-way radio systems, or telemetry hardware in topographically challenging areas.

Durable Galvanized Steel Construction for Harsh Outdoor Conditions
Built for longevity, this RSL tower is manufactured using hot-dip galvanized steel that resists corrosion, weather degradation, and mechanical wear. Whether exposed to rain, wind, snow, or sun, the structural components maintain their integrity over time. Each section features U-shaped legs that connect via lap splice, providing not only strength but also ease of installation with consistent bolt sizing and brace lengths throughout.

Modular Design Supports Fast Assembly and Future Modifications
Installation efficiency is a major benefit of the RSL system. The RSL70H39 is shipped in a knocked-down configuration, helping reduce freight costs and simplifying transport logistics. Each tower section is dimensionally uniform where it counts, so you won’t waste time hunting for custom bolts or mismatched braces. The included assembly drawings guide installers through a straightforward build process on-site.

Pre-Punched Mounting Points for Safety and Accessory Integration
This tower includes pre-punched holes to mount safety climb systems, grounding brackets, coax standoffs, and more. Optional accessories such as top plates, step bolts, grounding kits, lightning rods, or anti-climb brackets can be added for more advanced or secure setups. These features make the RSL70H39 a practical choice for utility companies, municipalities, and radio operators alike who need flexibility in system configuration.

Heavy-Duty Design Meets Public and Commercial Installation Needs
The Rohn RSL70H39 is built to meet the demands of government agencies, telecom installers, broadcasters, and advanced hobbyists. It supports long-term performance in permanent installations and can be adapted for use in remote surveillance, weather monitoring, or wireless ISP deployments. Backed by Rohn's engineering pedigree, it delivers the strength and reliability needed for mission-critical communication systems.

Scalable and Economical for Long-Term Infrastructure Planning
Like all towers in the RSL line, this 70-foot version is part of a system that scales from 20 feet to 100 feet. Start with your current needs and expand as your infrastructure grows. This particular configuration strikes an excellent balance between height, strength, and cost-effectiveness, making it a smart investment for organizations that require secure, elevated mounting systems.
