Awesome J mount!
This J-mount was very easy to assemble and worked perfectly for my Starlink Standard here in Kingston, Jamaica. The mount feels very secure and solid once installed, and I have full confidence in its stability. It mounted easily to the top of a concrete wall and offers excellent value for the price. The weight strikes a great balance heavy enough to feel strong and durable, but not so heavy that it’s difficult to handle or install on your own. I would definitely recommend this mount.

Solid and Sturdy
The Proxicast Pro-Grade J-Max mount was incredibly easy to assemble and install. It’s now holding a security camera, and it feels rock-solid and stable. The stainless-steel construction is clearly high quality—well-made, sturdy, and built to handle the elements. Only negative is that it should come with a cap for the open end. Otherwise, great product and worth every penny!

Sturdy, worth the money.
Great quality and worth the $. Replaced a cheap Chinese one that only lasted 3 years. This thing is great, should have bought it the first time. Easy install and comes with all the hardware you need. I have it mounted on my roof holding 3 antennas.

quality materials, disappointing tolerances
The material seems to be of excellent quality, and was easy to work with and install. Unfortunately, one of the selling points of this bracket, which is the ability to easily lock at 90 or 45 degrees, doesn't work very well. There is far too much slop in the bolt holes, so the mast is able to deflect substantially from vertical when assembled this way, and thus still relies on friction from bolt tension to hold it at the desired angle. This may or may not be a problem depending on the weight of whatever you're attaching. I'd still choose this over one of the cheap steel ones, however.

Proxicast are worth the high reviews that have been getting
I have a new gen3 starlink dish. Its well known that up until May2024 that the starlink pipe adaptor is garbage. So I needed to improvise. Proxicast has been wildly popular with early generation starlink dishes. I have one of the OAM starlink wall mounts, but the extension pipe is MUCH MUCH to short. The advantage of the OAM wall mount is a very firm connection to the dish itself. So comes in the improvise. Use the proxicast J mount to provide the extension. a standard well made u-bolt pipe adaptor clamp, and the OAM stalink pole/mount. As show in one photo is all three together. install on a facia of a steep metal roof comes next week. Pros: - high quality material - all nuts and bolts included - clear install instructions - pipe diameter is perfect fit (with a couple wraps of duct tape to fit snug) with starlink pole mount Cons: - with this kit, none - with proxicast in general, I wish they had a gen3 starlink pipe adaptor

VERY Good
I used this to mount a Ambient Weather station on the facia at the peak end of my roof. Using the provided holes I was able to get a solid mounting. I wasn't able to utilize the sloted holes for pluming the mast left or right due to there not being any good support at the center, but this was my builders fault. The other direction was easy to make ajustments and get plumb. I did chose to purchase stainless steel lag bolts as the provided bolts stuck to a magnet and appeared to be plated. My wife wasn't strongly in favor of the weather station and I didn't want to risk going to the doghouse because of a couple rust treaks in a few years. ;^) To get ideal wind information one should get height extensions that likely would require additional support, but in my case wind was only a minor consideration. Great product and stainless steel too.

Great quality mast. Used for a Helium Powered Weather Station
The quality of the mast is great for the price. It worked great for my WeatherXM station. It mounted and was very stable and sturdy. It has been through a few storms and hasn’t moved an inch. It came with all the hardware needed to mount and get everything in place. I highly recommend if you need a great quality mast.

Good quality, but 36" not as pictured
Yes, good stainless with nice finish and a strong bracket. But pictures of the 36" shows an asymmetric pole, which gives the option for either taller or farther from the mount. What was delivered is symmetric. If it is reversed, the payload is in exactly the same position. Oh well, it works, but it is not what they advertise.

El soporte quedó perfecto para la antena Starlink. Lo instalé en pared en un ambiente cercano a la costa, porque el primero que instalé hace un año no era de acero inoxidable y se oxidó muy rápido. Espero que esta me dure varios años.

I used this to mount my Starlink to the top of my house. The tube fits the mountain pole perfectly! Needed to drill a hole and file it down some to fit the square locking button on the dish, but that was pretty simple to do. Looks amazing on the house and is very sturdy. Highly recommended!

En mi caso tenía una pedestal en donde tenía instalada una antena UBITIQUI y la usé para aquí sujetar mi antena Starlink a través de este adaptador y ha funcionado correctamente , ya tengo más de 6 meses desde que lo instale y no he tenido problema alguno, incluso con las tormentas que ha habido últimamente.
