Review: It just works - Just what I needed to mount my antenna in the attic and aim it precisely.
Review: 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
*by M***T on March 5, 2014*

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.
