Ubiquiti UB-AM Networks Universal Antenna Mount
The Ubiquiti adjustable universal arm bracket can provide your wireless or networking device with a little height or stability without compromising its performance.
It can be attached on either the pole, when you want more control as to its height, or to the wall, if you want something that’s already fixed. You can slightly change the direction or the angle of the device even when it’s already mounted. This way, you can pick up reliable and strong wireless signals at any time.
