Rohn BRM440 Non-Penetrating Roof Mount

Heavy-Duty Roof Mount for Large Antenna Systems
The Rohn BRM440 Non-Penetrating Roof Mount is a commercial-grade mounting solution for securely installing antennas and communications hardware on flat rooftops. Designed to support a 36-inch tall, 4-inch outer diameter mast, this mount is built to handle substantial loads while preserving the integrity of your roof. It's an ideal choice for demanding installations in telecom, security, broadcast, or wireless internet environments.

Large Diameter Mast for Enhanced Load Capacity
The included 4" O.D. mast offers increased strength and rigidity compared to standard-size mounts, making it suitable for heavy antennas or larger arrays. Whether you're deploying a cellular repeater, point-to-point microwave dish, or high-gain Yagi system, the BRM440 can handle the job with confidence. The mast’s sturdy profile minimizes sway and ensures better performance in wind-prone areas.

No Roof Drilling Required for Installation
This roof mount installs without penetrating the roof surface, making it a go-to option for leased buildings, historic structures, or locations where structural modifications are restricted. It uses concrete blocks (not included) placed in a steel tray system as ballast, anchoring the mount in place without damage to roofing materials. This non-invasive approach protects your property and speeds up installation time.

Corrosion-Resistant Build for Long-Term Use
Constructed with hot-dip galvanized steel, the BRM440 is engineered for extended outdoor exposure. The galvanized finish resists corrosion from moisture, snow, and salt air—ensuring the mount remains reliable through years of service. It’s built to withstand the harshest elements while keeping your antennas stable and secure.

Quick Assembly and Broad Compatibility
The mount ships disassembled to simplify shipping and handling but is easy to assemble on-site with standard tools. Its 6'6" square base is designed with built-in steel angles to hold 16" concrete blocks, providing a balanced and solid footprint. This base setup accommodates a wide variety of antenna types, making it a flexible choice for any rooftop communication need.

Optimized for Professional Communication Applications
Whether you're working in wireless data delivery, emergency services, or broadcast operations, the BRM440 delivers the height and durability required for effective signal transmission. Its solid engineering, ease of use, and compatibility with large-scale antennas make it an excellent investment for professional-grade rooftop installations.
