2x2 MIMO Panel antennas are directional antennas that are very powerful at picking up weak signals in a specific direction. Because it can focus on a very narrow horizontal and vertical aperture, you need to move slowly to find the right direction. Even a 1-2 degree difference can make a huge difference.
keep the antenna facing the signal tower.
Any hotspot antenna is heavily dependent on its surroundings. To get better results, you have to consider antenna height, location, building clearance, line of sight, etc. Until you find the sweet spot that gives you the best returns.
If the device indicator light does not show, please check that the wires and device are tightly connected, and restart the device.
any antenna is just plug and play ,don't need any setup.
