Rohn BRM435 Non-Penetrating Roof Mount

Heavy-Duty Roof Mount for Large Antenna Systems

The Rohn BRM435 Non-Penetrating Roof Mount is purpose-built to handle large, high-performance antennas on flat rooftops without the need to drill or anchor into the structure. Featuring a 3-1/2" outer diameter mast and a 36" height, this mount supports heavier payloads and higher Effective Projected Areas (EPA), making it ideal for commercial communications, cellular, and broadband installations. It's a powerful and roof-safe solution for demanding applications.

Robust Mast for Serious Antenna Installations

At the core of this mount is a heavy-duty 3-1/2" O.D. mast that stands 36 inches tall, offering the strength and clearance needed for advanced antenna systems. The large-diameter mast ensures maximum rigidity, reducing sway and maintaining reliable antenna alignment in all conditions. This makes it ideal for directional antennas, large microwave dishes, or multi-unit setups where precision and load-bearing capacity are crucial.

Non-Penetrating Design with Ballasted Support

The BRM435 is engineered with a spacious frame designed to be stabilized using standard 16" concrete blocks (not included). This ballast approach secures the mount in place without breaching the roof membrane, preserving the integrity of the surface and complying with strict building codes or lease agreements. Its footprint is optimized for weight distribution, ensuring secure placement on rooftops even under wind load.

Galvanized Steel Frame for Long-Term Weather Resistance

The frame and mast are hot-dip galvanized to withstand the toughest outdoor environments. This corrosion-resistant coating protects the structure from rain, snow, UV exposure, and coastal conditions, making it suitable for long-term use in any climate. Whether you're installing it in a humid metro or dry high-altitude location, the BRM435 holds up under pressure.

Designed for Easy Transport and Setup

This mount ships unassembled for efficient transport and can be put together quickly on-site using basic tools. Once the ballast blocks are in place and the mast secured, the BRM435 becomes a rugged, ready-to-deploy base for your antenna systems. The simple assembly process helps reduce downtime and labor costs during installation.

Ideal for Wireless, Surveillance, and Testing Applications

From fixed wireless networks to rooftop surveillance cameras and field testing applications, the BRM435 is a dependable platform for any antenna project where roof penetration isn’t an option. It's an especially smart choice for contractors and integrators who need flexibility in system design and deployment.
