Rohn 25SS040 25G 40' Self-Supporting Tower Kit

Reliable 40-Foot Self-Supporting Tower for Critical Antenna Installations
The Rohn 25SS040 25G Self-Support Tower Kit offers a solid and dependable 40-foot freestanding tower designed to support your antenna systems without requiring guy wires. Ideal for locations where space is limited or guyed configurations are impractical, this kit is tailored for amateur radio users, surveillance systems, public utility communication, or commercial-grade antenna setups. It’s a complete, heavy-duty solution built for secure, long-term installations.

Built for Structural Integrity in Self-Supporting Use Cases
This self-supporting tower system is constructed with Rohn’s time-tested 25G-series components, known for their durability and ease of installation. It features 1-1/4" OD, 16-gauge tubular steel legs and 5/16" solid bracing, all forming an 11.25" equilateral triangular geometry. Every section undergoes hot-dip galvanization after fabrication, providing enhanced resistance to corrosion in a wide range of environments.

Complete Tower Kit Simplifies Installation Planning
Included in the 25SS040 tower kit are three 10-foot standard 25G sections, one 9'9" tapered top section (25AG2) with integrated pipe, a 5-foot short base (SB25G5) for concrete embedding, and an ACWS anti-climb warning sign kit. Every tower section arrives with the required hardware pre-packed, including bolts and nuts for secure connections. The kit is engineered for simplified assembly and compatibility with standard Rohn guidelines and accessories.

Proven Double-Bolted Joint Design Enhances Stability
One of the standout engineering features of the 25G tower system is the use of double-bolted joints at each tower section connection. This method has been proven superior for maintaining structural rigidity and resisting torque, making it a go-to choice for serious tower installations. The bottom base can only be connected at one end for concrete installation, ensuring secure ground anchoring.

Tapered Top Section with Integrated Mounting Pipe Adds Versatility
The included 25AG2 top section is specially designed with a tapered profile and a built-in mounting pipe. This allows for easy integration of antennas, mounts, or other vertical components without needing separate adapters. It measures 9 feet 9 inches in total and provides a clean, secure termination for the top of your tower.
