Proxicast J-Max Stainless Steel J-Arm Antenna Mount Pole 1.5" x 36"
Product description
Heavy-duty construction: bracket and J-arm are built from 304 stainless steel to resist rust and corrosion in outdoor settings.
What’s in the box: the kit includes the J-arm bracket, the 1.5" x 36" J-pipe, mounting base, locking pin, and all required stainless mounting hardware so you can install immediately.
Locking pin and angle options: the mount provides a pivot with a removable locking pin to secure the arm at 0°, +45° and -45°, improving stability for larger antennas.
Adjustable pivot and slide: the arm slides and pivots to let you fine-tune the J-pipe location for optimal reception and to clear obstructions. The base can be attached to flat or sloped surfaces.
Universal compatibility: designed to accept a wide variety of antenna types — 4G/5G, Wi‑Fi, TV/HDTV, satellite dishes, Helium miners, weather stations, ham and CB antennas — and to serve as an extension when a longer standoff is needed.
Reversible J-pipe: the pipe can be reversed to increase wall standoff distance for mounting flexibility and better clearance from eaves or gutters.
Pros
- 304 stainless steel resists corrosion
- Includes all mounting hardware
- Locking pin secures common angles
Cons
- Pivot hole can be slightly oversized for some bolts
- Some base holes sit behind the arm when assembled
- May need tape or shims to snug certain pipe fits
VerdictA robust, all‑stainless J-arm mount that resists corrosion and arrives with the fasteners you need. The locking pin and slide/pivot let you lock heavier antenna gear at three common angles, and the reversible J-pipe increases wall clearance. Small fitment nitpicks aside, this is a dependable choice for outdoor antenna and access point installations.

High quality — worth paying a bit more
Mounted an access point near my roof peak to expand outdoor Wi‑Fi and the coverage improvement was dramatic. Stainless steel feels well made and durable; glad I upgraded to this model.

Very well made
I use it to hold a Davis weather station. Fully adjustable and very steady — exactly the stability I required.

Recommended for coastal installs
This mount fit my Starlink perfectly. I put it on a wall near the coast after a previous non‑stainless bracket rusted out; hoping this one lasts for years.

Solid J-arm, easy install
Simple to put together and worked flawlessly for my Starlink unit in Kingston. Feels sturdy on a concrete wall and gives me confidence in long‑term stability. Good weight — heavy enough to be robust but manageable for solo installation.

Used with my Starlink dish
Mounted this to extend my Starlink pole — added the optional extension and it has performed without issues. Clean stainless finish holds up well.

Nice stainless, minor fit issue
Love the corrosion resistance and the extra height to clear eaves. One gripe: the square hole for the pivot bolt is a touch large, so the carriage bolt can rotate unless you hold it while tightening.

Exactly what I needed to extend my Starlink mount
Used this J mount with a Starlink wall bracket and a U‑bolt adapter to gain extra reach. All bolts and instructions were included, materials are top notch, and the pipe diameter matched well with a little tape for a snug fit.

Good gauge stainless
Worked great for my Starlink install. Solid stainless thickness and well fabricated.

Sturdy support for outdoor AP
Chose stainless over aluminum to handle added mast tubing and weather exposure. Installation was straightforward, though a couple of base holes sit behind the arm so you may need to assemble in place.
