Rohn JRM23810HC 120" x 2 3/8" Non-Penetrating Roof Mount

Roof Mount System for Antennas Without Roof Damage
The ROHN JRM23810HC is a heavy-duty non-penetrating roof mount built to support antennas and communication equipment without compromising your roof’s integrity. It includes a 10-foot mast with a 2-3/8" outer diameter and a complete hardware carton for fast, secure assembly. Designed for ballast anchoring using standard concrete blocks, this mount is ideal for rooftop installations that require stability without permanent fastening or drilling.

Non-Invasive Mounting Solution for Flat Roof Surfaces
This system allows professionals to install antennas without penetrating the roof membrane, preserving warranties and preventing leaks. The frame uses ballast blocks (not included) to hold the structure in place, making it a smart choice for leased properties, commercial buildings, and locations requiring non-destructive installation. Its non-penetrating design ensures long-term reliability without risking structural damage.

Includes 10-Foot Mast for Extended Height and Signal Reach
The JRM23810HC features a 120-inch mast with a 2-3/8" OD, ideal for mounting antennas that benefit from additional elevation. Whether you're installing directional wireless antennas, point-to-point systems, or surveillance gear, the increased height helps maximize signal clarity and line-of-sight performance. The steel construction ensures durability while supporting a range of antenna sizes and configurations.

Engineered for Stability Using Standard Concrete Ballast
This mount uses a ballast system based on 16" nominal concrete blocks to keep the structure firmly grounded. The wide 62" x 62" frame evenly distributes weight across the rooftop surface to minimize pressure points and increase wind resistance. It provides a rugged platform for temporary and semi-permanent installations in demanding conditions.

Compact Footprint for Easy Installation on Crowded Rooftops
Despite its tall mast, the JRM23810HC maintains a compact footprint, making it ideal for installations where rooftop space is limited. With a 62-inch width and length, the base accommodates sufficient ballast without interfering with other rooftop systems. The mount ships disassembled for convenient handling and assembles easily with the included hardware kit.

Supports Add-On Safety and Roof Protection Accessories
For added protection, installers can use optional accessories like the JRMMAT or JRMPAD to reduce wear on the roof membrane. ROHN also offers the SCK150 safety cable kit to provide additional securing in high-wind regions. These accessories (sold separately) enhance both safety and longevity of the installation.

Trusted by Installers for Telecom, Security, and Wireless Projects
Used across the telecommunications, broadcasting, security, and wireless access industries, this mount delivers the reliability professionals expect. It’s a dependable rooftop solution for Wi-Fi, LTE, 5G, point-to-multipoint systems, and more—especially when structure protection and signal performance are top priorities.
