Proxicast J-Max Aluminum Antenna Mount 1.5" x 18" J-Pipe

The Proxicast Pro-Grade J-Max is a 100% solid, rustproof aluminum antenna mount with an adjustable pivot and locking pin that secures a 1.5" x 18" J-pipe for reliable outdoor installations.

This heavy-duty mounting kit combines aircraft-grade 5052 aluminum components with 304 stainless-steel fasteners to deliver a corrosion-resistant solution for mounting antennas on walls, eaves, or roofs. Designed to accept a wide range of aerials — from TV and WiFi to 4G/5G, weather stations, ham radio, and satellite accessories — the J-Max system offers reversible J-pipe standoff options and a locking pivot for precise alignment and long-term stability in exposed locations.

How does the J-Max keep antennas stable in windy conditions?

The mount uses solid 5052 aluminum construction plus a unique locking pin to resist bending and rotation under load. The pivot can be set at 0°, +45°, or −45° and locked into place to prevent movement once aligned.

• Solid aircraft-grade 5052 aluminum arm and bracket for strength without added weight
• Locking pin increases shear resistance at pivot points
• 304 stainless-steel bolts and washers resist corrosion and seizure
• Reversible J-pipe provides additional standoff for leverage control

Will this mount fit my antenna and mounting surface?

The J-Max is built as a universal bracket to accept most antenna masts and attachment patterns. The included J-pipe is 1.5" in diameter and 18" long, suiting common mast sizes and allowing compatibility across antenna types and brands.

• 1.5" x 18" J-pipe mast fits standard clamps and U-bolts
• Flat or sloping wall/eave/roof bases accommodate simple bolt-on installation
• Reversible J-pipe increases standoff for larger or obstructed installations
• Works with TV, HDTV, satellite, 4G/5G, WiFi, ham, CB, and weather station gear

How easy is it to install and adjust on-site?

Installation is straightforward for anyone comfortable with basic hand tools and roof or ladder work. The design lets you pivot and slide the J-pipe for fine-tuning, then secure the position with the locking pin and stainless fasteners.

• Pre-drilled bracket holes for fast mounting to common surfaces
• Adjustable pivot and slide to fine-tune mast angle and reach
• Stainless hardware included; no additional rust-proof components required
• Reversible configuration reduces need for custom standoffs

What maintenance does the Proxicast J-Max need over time?

The corrosion-resistant materials minimize upkeep; routine inspections ensure fasteners remain tight and the locking pin is engaged. If you live in a coastal or high-saline area, periodic checks and light cleaning will extend service life.

• Inspect stainless bolts annually and retorque as needed
• Clean salt or debris buildup to prevent abrasive corrosion
• Verify locking pin engagement after storms or ice events
• Replacement hardware is standard sizes and readily available

Who is this for: The Proxicast Pro-Grade J-Max is for homeowners, installers, and hobbyists who need a durable, corrosion-resistant antenna mounting solution that adapts to multiple antenna types and mounting surfaces. It suits residential and light-commercial installations where long-term performance, easy adjustment, and rustproof construction are priorities, especially in climates where steel mounts would corrode quickly.
