Where can I get a generic/universal "ball-joint" mount like this? Ubiquiti stopped including these with their newer antennas. All I can find are crappy little GoPro knockoff mounts, too small and not made for 24/7 outdoor use.

Ubiquiti used to include these little ball-joint mounts that gave you 360 degrees of movement on your antennas.

Now they don't include anything like this and instead just let you strap directly to a pole. But if you have an existing pole that you can't move or angle, you're shit outta luck.

I can't seem to find anything like this. Am I using the wrong search terms?
