MIMO technology and Aftermarket Antennas question

by Usaball4848 Mar 4, 2019 3:54PM PST

I bought an aftermarket Alfa APA-M25 antenna to replace one of the antennas on my TP-Link C2300 that has MIMO technology. Did I need to buy an antenna that supports MIMO technology? Does it even matter?

I actually bought two of the mentioned above antennas. Will I be able to utilize MIMO technology this way if I attach two of the aftermarket antennas? Or do I need to have all three of the original antennas attached?

If I were doing this

I'd replace them all since MIMO can do beam forming and if the antennas don't match the beam is wacko.

My background does include antenna work, not design but testing in many bands over the years.
The last time we used diversity which you can read about at https://en.wikipedia.org/wiki/Antenna_diversity
In that system we used matched lines and antennas.
