The tower is part of ROHN's widely recognized 25G Series, which is known for its durability, reliability, and widespread adoption in both amateur and professional communications. This model is specifically built for installations where ice loading is not a concern.
Key Features:
Height: 40 feet (12.19 meters)
Self-Supporting Design: No need for guy wires, ideal for smaller spaces
Modular Section Construction: Allows easy assembly and disassembly
Lightweight yet Durable Steel Construction
Corrosion Resistance: Hot-dip galvanized steel to resist rust and wear
Application Versatility: Suitable for amateur radio, Wi-Fi systems, television antennas, surveillance cameras, and more
No Ice Loading Rating: Built for environments where ice accumulation is minimal or non-existent
Construction Quality and Build
The ROHN 25SS040 is constructed using hot-dip galvanized steel, a process that coats the steel in a protective layer of zinc to resist corrosion. This ensures the tower's longevity, even in harsh weather conditions like heavy rain or humidity.
The tower is built using modular 25G series sections that bolt together securely. Each section features a triangular lattice design that balances weight with strength, providing superior load-bearing capabilities while remaining lightweight for transport and assembly.
Build Highlights:
Tubular Steel Bracing: Reinforces the structural integrity of each tower section.
Welded Joints: Precision-welded for durability and safety.
Safety Factor: Designed to meet or exceed ANSI/TIA structural standards for communications towers.
The lattice construction also ensures minimal wind resistance, allowing the tower to remain stable even in moderate winds. ROHN has a strong reputation for adhering to engineering and safety standards, making this tower a reliable choice for professionals.
Installation Process
One of the standout qualities of the ROHN 25SS040 is its straightforward installation process. The modular design allows sections to be stacked and bolted together, simplifying both transport and assembly.
Installation Steps:
Foundation Preparation: Proper foundation work is crucial for stability. This includes digging and pouring a concrete base according to ROHN's engineering drawings and specifications.
Assembling the Sections: The tower sections come pre-fabricated and are bolted together at the site.
Anchoring and Leveling: Ensure the tower is leveled during the installation process to guarantee structural integrity.
Equipment Attachment: Attach antennas, dishes, or other equipment according to weight and wind load guidelines.
The tower comes with detailed assembly instructions, making it approachable for installers with intermediate to advanced knowledge. However, professional installation is recommended to ensure proper safety procedures are followed, especially when working at heights.
Tools and Accessories Required:
Standard wrenches and bolts (provided)
Safety harness and climbing gear
Concrete and anchoring materials for the base
Performance and Durability
The ROHN 25SS040 performs exceptionally well in environments where ice loading is not a factor. Its sturdy steel construction allows it to support moderate antenna loads without additional guy wires. This is ideal for urban or suburban areas where space is limited.
Load Capacity:
While the specific weight-bearing capacity depends on wind speed and antenna surface area, the 25G series towers are engineered to handle moderate loads (e.g., a single Yagi antenna, small dishes, or lightweight communication arrays).
Wind Resistance:
The tower's lattice structure provides excellent wind resistance. Under normal conditions, the ROHN 25SS040 remains stable and reliable.
Longevity:
Thanks to its hot-dip galvanized steel construction, the tower boasts excellent rust and corrosion resistance, allowing it to remain functional for decades with proper maintenance.
