Rohn 55SS020 55G Series 20' Self Supporting Tower Kit

Complete 20-Foot Self-Supporting Tower Kit for Reliable Ground-Based Installations
The Rohn 55SS020 is a 20-foot self-supporting tower kit designed for applications that require short, stable vertical elevation without the need for guy wires. This package includes everything needed for a standalone install: two 10-foot 55G standard tower sections, a short base for concrete embedment, a top plate, and an anti-climb warning sign kit. Engineered for quick deployment and structural stability, this compact tower is ideal for light-duty antennas, monitoring equipment, or rooftop-to-ground communications links.

Ideal for Locations Where Guying is Not an Option
For installation sites where guy wire anchoring is restricted or space is limited, a self-supporting tower like the 55SS020 provides a secure, efficient solution. The included SB55G short base section is designed for direct embedment in concrete, delivering a solid footing that supports the tower without additional bracing. It’s ideal for urban, residential, or industrial environments where guyed towers are impractical or prohibited.

Built with Heavy-Duty Galvanized Steel for Long-Term Outdoor Use
All included tower sections and components are fabricated from durable steel and hot-dip galvanized after manufacturing to resist corrosion in outdoor conditions. The 55G series design features 1-1/2" OD 11-gauge tubular legs and 7/16" OD solid bracing, forming a strong triangular truss system. This design distributes load efficiently, making it suitable for small antennas and lightweight payloads that require elevation and durability in harsh weather environments.

Compact 20-Foot Height Supports Versatile Communication Needs
At 20 feet, this tower offers modest height for low-profile applications such as VHF/UHF antennas, wireless camera systems, broadband access points, or point-to-point wireless links. Its manageable size also makes it easier to transport, assemble, and install with minimal crew and equipment. For end-users needing short-haul signal elevation with strong structural reliability, the 55SS020 is a dependable option.

Factory-Matched Components Ensure Consistent Performance
This kit includes a matched APL55G top plate, SB55G short base section, and two 10-foot 55G tower sections—all engineered to work together for optimal strength and stability. The anti-climb warning sign adds a layer of visual safety compliance. Each tower section ships with the necessary bolts and hardware, so everything is ready for assembly upon delivery. The kit ships via freight to accommodate the steel structure’s size and weight.

Double-Bolted Joint Design Enhances Structural Integrity
Rohn’s 55G tower sections are connected using a proven double-bolted joint system, increasing strength and resistance to twisting or flexing under load. This connection method outperforms single-bolt systems in durability and alignment, making the 55SS020 an excellent choice for applications where structural dependability is key—even at modest elevations.

Perfect for Amateur Radio, Surveillance, or Rural Wireless Installations
Whether you’re setting up a short-range broadcast system, a weather station, or a secure surveillance mount, this self-supporting 20-foot tower offers a low-maintenance, long-term solution. Its rugged build, compact footprint, and hassle-free setup make it a go-to option for entry-level tower users and professionals alike.
