Rohn RSB03 RSL Series Short Anchor Base - Section 3

Compact and Cost-Effective Tower Foundation Option
The Rohn RSB03 is a purpose-built short base section designed specifically for RSL tower systems where Section 3 serves as the starting point at ground level. This anchor base is a smaller tower segment that acts as a foundation element, intended to be embedded directly into concrete. Its compact form factor makes it a cost-effective alternative for structural support when a full-length anchor base is not required.

Engineered for Reliable Tower Support
As part of the Rohn RSL tower series, the RSB03 short base delivers robust support through its welded steel construction and integrated bracing. The built-in horizontal brace is essential during installation, allowing the section to be perfectly leveled before concrete is poured. Once the base is set, it becomes a fixed point of reference for the entire tower, ensuring vertical alignment throughout the structure.

Designed for Section 3 Ground Installations
This model is specifically compatible with installations where the RSL Section 3 is the bottom section of the tower. Its geometry and bolt patterns are designed to integrate directly with the tower leg and brace layout of the RSL Series. This provides a seamless structural transition from foundation to tower, preserving alignment and structural integrity.

Critical Installation Requirements
The RSB03 must be leveled with absolute precision during the concrete pour. It cannot be adjusted once the concrete sets, which makes accurate initial placement crucial. Installers should take care to use proper leveling equipment and concrete setting techniques to ensure optimal alignment. Once properly set, the base provides a stable and permanent support structure for the tower above.

Ideal for Lightweight and Mid-Height Tower Projects
Because of its form factor and design intent, the RSB03 short base is well suited to smaller RSL tower configurations—typically those used in broadband, public safety, and telemetry applications. Its integration into the concrete foundation keeps the base cost low while delivering dependable long-term performance.

Built for Durability in Harsh Environments
Like all Rohn RSL tower components, the RSB03 is hot-dip galvanized for corrosion resistance. This allows it to withstand exposure to moisture, temperature variation, and other environmental stressors without degrading. It is engineered for long-term outdoor use and meets industry standards for grounding and tower base installations.
