Not a good product. You can't tighten the screws enough to keep it from falling down.I used blue thread lock on it too!!I mounted a Weboost Range omni antenna with the 13" pole to it.I even left out the spring mount to save weight.

These are very lightweight, I would not recommend using anything over a 24" antenna & nothing heavyduty! The plastic knobs look great but don't hold well, possibly loc tite them as well as the mount bolts. 2 stripped during my install but I pushed them honestly & they are good mounts just very light duty.

I like this set up. Seemed to be the best of all the Antenna mounts I've seen. I like it cuz it's not spot specific ... comes with every possible mounting option, so even if you decide to move it later, then your covered. Pretty sturdy to.

The knob on this bracket will allow you to tip down an antenna, but it'll only go about 75 degrees from vertical. There's a "dimple" on the one half that snugs into a series of holes on the part that holds the UHF connector, and there just aren't enough holes in the rotating bit to let it go all the way down to horizontal from the vertical position. This also means you can't use this bracket to mount on a vertical post and have your antenna completely vertical.

Well, I am going to try and use this and see what happens. The sheet metal is too thin to stand up to much vibration or stress. Once the antenna is on the mount (and my antenna is just 10 inches high), the mount flexes and vibrates. The screw adjust vertical pivot is just tightened by two small screws and you can move it around - even when tightened!. The rotational adjustment has detents (good idea) but they are not aligned with the frame well, and when they are tightened and the antenna is perpendicular to the mount, the antenna is off vertical. Very cheap and poor quality. Certainly would not buy it again.
