Rohn JRM35010HC Non-Penetrating Roof Mount

Non-Penetrating Roof Mount for Large-Diameter Antenna Installations
The ROHN JRM35010HC is a heavy-duty non-penetrating roof mount system built to support antennas requiring large-diameter mast support on flat rooftops. Featuring a 10-foot galvanized steel mast with a 3-1/2" outer diameter and a durable 62" square ballast base, this system is ideal for large antenna arrays used in telecom, broadband, public safety, and enterprise networks. It ships with a hardware carton for simple on-site assembly and installation.

Designed for Roof Integrity with Ballast-Only Installation
This mounting system avoids roof penetration entirely, relying on concrete block ballast (not included) to anchor securely without fasteners or adhesives. The base supports up to 12 nominal 16" concrete blocks, allowing the system to remain stable even in challenging wind conditions. Its non-penetrating design is perfect for leased facilities, membrane rooftops, and locations where roof warranty preservation is a concern.

10-Foot Mast with 3.5-Inch Diameter Supports Heavier Loads
The included mast is constructed of galvanized steel with a 3.5" outer diameter and thick wall section, making it well-suited for mounting large antennas such as microwave dishes, broadcast panels, or multi-sector radio systems. The 10' height helps lift equipment above surrounding obstacles, improving line-of-sight for optimal RF signal propagation in rooftop deployments.

62-Inch Square Base Increases Stability in Windy Conditions
The wide base evenly distributes weight across the rooftop and minimizes pressure on the surface, enhancing overall stability. Whether used in temporary or permanent applications, the steel frame holds position securely when properly ballasted. Galvanized components help resist corrosion and extend the life of the mount in harsh outdoor environments.

Ships Disassembled for Easy Handling and Rooftop Setup
The JRM35010HC ships broken down on a single skid and weighs about 50 lbs fully assembled (excluding ballast). The included hardware carton simplifies job site setup, and the modular design makes it easier to move through tight access areas such as doorways or elevator shafts. This makes the system particularly convenient for contractors and field teams.

Compatible with ROHN Roof Protection and Safety Accessories
Installers can pair this unit with ROHN’s JRMMAT (1/8") or JRMPAD (3/8") to add a protective buffer between the steel frame and the roof surface. The JRMMAT consists of four 72" x 18" sections forming a 72" x 72" pad under the base. In high-wind environments or mission-critical installations, the SCK150 safety cable kit (3/8" x 150') adds an extra level of anchoring security.

Reliable Solution for Commercial Wireless and Infrastructure Use
The JRM35010HC is trusted across industries that demand secure, stable antenna installations without compromising structural integrity. Whether you’re building out a rooftop wireless ISP system, a microwave backhaul, or a broadcast solution, this roof mount offers the strength, flexibility, and non-invasive footprint that contractors and engineers need.
