What is MIMO Omni antenna?

Omni-directional antenna products specifically designed for use with multi-port MIMO / MANET radio systems. These products feature multiple discrete antennas within the radome, each with its own RF connector.698-4000MHz Mimo OMNI Antenna is popular in 5G market.

Does MIMO antenna really work?

MIMO antennas will help condition the outdoor signal and get you better data rates. But if the signal outside your building isn't usable to begin with, MIMO antennas might not help. You can certainly still give the MIMO antenna a shot, but you may still be unable to connect.

What are the disadvantages of MIMO?

The main disadvantage of MIMO system is that the multiple antennas required extra high cost RF modules. The extra RF modules increase the cost of wireless communication systems. In this research, the antenna selection techniques are proposed to minimize the cost of MIMO systems.
