It just works
Just what I needed to mount my antenna in the attic and aim it precisely.

Great product with easy installation
Product works perfectly for my newly purchased HD TV antenna. Item was a breeze to assemble and install (includes mounting bolts and roof patches) and appears to be very well-made and sturdy. Overall pole size is in the 1-inch range, which will work perfectly for smaller HD TV antenna applications. It should be noted that the overall size (length) was a bit shorter than I envisioned, so if in doubt go with the next size up..

Great product
This worked out exactly as we needed it to. Installation was pretty straight-forward and everything we needed was included for installation. The only thing that prevents me from giving it five stars is the long term stability of the adjustable joint. The mast pivots at the joint and is secured by two bolts. The lowest one is just a single hole but the second bolt slides through the arc. I tightened it down as best as I could but since this is exposed to weather I'm concerned that the bolt could loosen over time, especially with wind, and cause the mast to slip. I'm not a big fan of climbing up onto our roof in the first place so I'm not looking forward to a visit up there in a few weeks to check that single bolt. I think a locking washer or outdoor rated gasket would help but there's not enough length to the bolt to add one of my own.

Solid J-Mount extender. Works well!
This mount is perfect for what I needed it for -- to mount the BoostWaves Antenna to the side of my roof. It is strong and can be easily manipulated into position and then tightened down. It is powder coated too so it will last forever without rusting. I needed more height than what this offered, so I went to my local hardware store and bought an 8-foot piece of 1" diameter PVC tube to use as an extender. Much cheaper than buying a metal extender here on Amazon and it will last just as long. I extended my antenna 6 more feet higher. I drilled holes into the top of the PVC tube and ran wire to all four corners of my roof to keep the pvc steady in the wind. No problem! Simply put the PVC into the top of this mount and bolt it in. Works like a charm and I definitely recommend this J-Mount. Just be careful it fits your antenna diameter. The maximum diameter to insert any pvc tube, extender tube or antenna tube into the top of this mount is 1 inch! Of course, you can buy a slightly smaller diameter, but DO NOT buy a larger diameter extender unless you have an adapter to scale it down to 1" or smaller.

Antenna catches with stand
I put my antenna on this stand and on the back porch and it picks 176 channels including ABC,NBC,CBS and even FOX. FOX I could not catch without this stand.

I was looking for a nice heavy duty pole and was somewhat disappointed with the quality. It was not heavy and I did manage to put some wrinkles in the pole just attaching the antenna. Where I tightened down the clamps on the antenna it did but dings in the pole. I guess the antenna won't slide up or down with it bent like that. The paint was good and the way it mounted to the home was good.

Performing well
I'm a ham radio operator. I used this to mount a VHF/UHF J-Pole antenna to the gable of my house. Easy-peasy. Other masts I tried had a thicker diameter (designed for satellite dishes), and did not fit my antenna mount. So I'm pleased this comes in a 1" diameter. It has withstood heavy winter winds (the antenna flexes, but no harm done). Good value for money. Only complaint was the weather-seal rubber material included. It had melted during shipping. Nasty, sticky stuff that is hard to wash off and will ruin your clothing if you're not careful.

Great for PWS
Got this as a mount for my personal weather station (an Ambient Weather WS-2000) and it’s worked like a charm for almost 2 months, including the inland impacts from 2 tropical storms. The instructions maybe could’ve been a bit better, but it came with everything needed to quickly install on my shingle roof, including tar pads to avoid leaks.
