Rohn FR25G 25G Flat Roof Mounts

Flat Roof Tower Mount for ROHN 25G and 45G Series
The ROHN FR25G is a robust base designed to securely anchor ROHN 25G or 45G tower sections to a flat roof. This flat roof tower mounting solution is ideal for installations where ground space is limited or rooftop positioning is required. It allows a tower section to be directly attached to a flat surface, provided the structure is reinforced to handle the vertical load and dynamic stresses associated with antenna and tower installations.

Reinforced Rooftop Antenna Mounting System
This base must be installed on a water-tight and structurally reinforced flat roof. Since the FR25G does not act as a self-supporting base, it requires additional guying or wall brackets to stabilize the tower. This makes it suitable for installations where rooftop access is available, but ground anchoring is not feasible. Always ensure that the flat roof has been inspected for load-bearing capacity before proceeding with installation.

Double-Bolt Joint Construction for Maximum Stability
One of the most critical features of the FR25G is its double-bolt attachment method for tower legs. This connection method is proven to be significantly stronger and more secure than single-bolt alternatives. The double-bolt joints ensure a reliable structural bond between tower sections, which is vital in high wind or load-bearing environments. It enhances both the vertical rigidity and lateral strength of the tower system.

Optimized for Guyed or Bracketed Tower Applications
The FR25G base supports both guyed and wall-bracketed tower configurations. It is not designed for freestanding tower systems. Instead, it offers a foundational attachment point that works in tandem with guy wires or wall mounts to complete the tower’s structural triangle. This design is common for broadcast, communications, and antenna systems installed in space-restricted urban and industrial environments.

Height Limitations Based on Guying and Roof Layout
When using the FR25G for a roof-mounted tower system, overall tower height may be limited by the layout of the rooftop and available guying options. Since guy line length and anchor positioning are crucial to tower stability, these factors should be planned in advance. A professional structural assessment is always recommended before finalizing the height and guy configuration.

Built for Compatibility with ROHN Tower Systems
Engineered specifically for the ROHN 25G and 45G tower series, the FR25G integrates seamlessly with standard tower sections. It offers reliable structural compatibility and simplifies the installation process for installers familiar with the ROHN tower ecosystem. Whether you are mounting a communications antenna, microwave dish, or weather instrumentation, this base provides a durable starting point.

Ideal for Professional Tower Installations on Flat Roofs
This base plate is a staple component for contractors, broadcasters, amateur radio operators, and telecom professionals looking to install reliable towers in non-ground-based locations. With its solid construction, precise compatibility, and reinforced mounting design, the FR25G is a trusted solution for rooftop tower applications.
