Rohn BRM430 Non-Penetrating Roof Mount
Best damage-free mounting solution for roof-mounted communication equipment.
The Rohn Non-Penetrating Mount offers a robust, damage-free solution for securing communication equipment like satellite dishes or wireless antennas to a roof. Its base is galvanized for superior corrosion resistance, ensuring longevity. Constructed from durable 16 or 14 gauge steel, this system includes the necessary mast, though anchoring requires separate 16" nominal concrete blocks. Available configurations support various mast diameters, including 1.25", 1.5", and 2.38", with options for Pre-Galvanized or Hot-Dip Galvanized finishes depending on the model selected.

What customers say
Customers highly value the Rohn BRM430 for its professional grade, heavy-duty construction and exceptional build quality. The primary appeal is the non-penetrating design, which offers peace of mind by protecting roof warranties and preventing leaks, justifying the significant investment. This mount provides a supremely stable platform for antennas, especially in high wind zones, provided ballast requirements are strictly met. While assembly is straightforward, the unit's size requires careful handling. The main friction point is the high initial cost and the added expense and effort of sourcing necessary concrete ballast. Overall, it is the preferred choice for serious users needing maximum, non-invasive security for critical communication setups.
Know before you buy
No, the Rohn BRM430 is a non-penetrating mount. It is designed to sit securely on your roof surface without requiring any drilling or structural modifications.
You will need to source 16-inch nominal concrete blocks separately to act as ballast. These blocks are placed on the base frame to provide the necessary weight to keep the mount stable against wind loads.
Yes, the mount comes with the mast included. You should verify that your specific equipment diameter matches the supported range of 1.25 inches to 2.38 inches before installation.
The galvanized finish is specifically applied to resist corrosion and rust. It is highly effective for outdoor, long-term exposure, ensuring the structural integrity of the steel remains intact over time.
The base footprint is approximately 3 feet by 3 feet. This size provides a stable foundation for your communication equipment while remaining compact enough for most standard flat roof layouts.
