Rohn JRM23805HC Non-Penetrating Roof Mount

Heavy-Duty Non-Penetrating Roof Mount for Antenna Systems
The ROHN JRM23805HC is a non-penetrating roof mount system designed to support antenna masts without drilling or damaging the roof surface. This versatile platform includes a 5-foot tall, 2-3/8" outer diameter steel mast and all necessary hardware in one consolidated carton. Commonly used for wireless, broadband, PCS, and other communications applications, it offers a stable and secure solution for roof-mounted installations.

Ballasted Design Secures Equipment Without Roof Damage
This mount functions as a ballast-style base, requiring no permanent anchoring into roofing materials. Instead, it relies on concrete blocks (not included) placed in its base frame to keep the system steady and secure. The design accommodates up to 12 standard concrete blocks, providing ample weight to stabilize antennas in a variety of environmental conditions while keeping the rooftop intact.

Supports Antenna Masts Up to 10 Feet in Height
The included mast stands 5 feet tall and measures 2-3/8" in outer diameter, making it suitable for a wide range of antenna sizes and loads. The JRM platform can be adapted to accept mast extensions up to 10 feet tall, and is also compatible with alternative mast diameters such as 2", 2.5", and 3" (sold separately). This flexibility makes it a go-to mount for professional telecom, surveillance, or point-to-point antenna deployments.

Ships Disassembled for Easy Handling and Installation
The JRM23805HC ships disassembled in a single carton or skid, allowing for easier transport to rooftops or job sites. Once assembled, the system weighs approximately 50 lbs (not including ballast), making it manageable to install while still providing the strength needed for long-term use. All necessary mounting hardware is included, making setup fast and straightforward.

Optional Protective Mats and Safety Kits Available
To further safeguard your roofing surface, ROHN offers optional accessories such as the JRMMAT (1/8" thick) or JRMPAD (3/8" thick). These mats act as a cushion between the mount and roof, protecting membrane surfaces from abrasion. For installations in high-wind areas or tall mast configurations, the optional SCK150 safety cable kit (3/8" x 150') provides an extra layer of security.

Ideal for Telecom, Broadband, and Surveillance Installations
The JRM23805HC is widely used across telecom, WISP, and broadcast sectors for rooftop antenna mounting where non-invasive, temporary, or semi-permanent installations are needed. It's a practical solution for data backhaul, microwave, LTE, and Wi-Fi antenna setups where preserving rooftop integrity is just as important as structural support.

Durable Construction for Long-Term Outdoor Use
With its galvanized steel components and robust design, the JRM23805HC withstands harsh weather and environmental exposure. Whether you're building a new site or upgrading an existing one, this mount provides a dependable platform that resists corrosion, maintains its structural form, and minimizes rooftop wear.
