Wireless Diversity on the BaseBox2

Good Evening,
I need a Router with 3-4 Antennas in the 2.4 Ghz band for a project, where I need Wireless Diversity.
I’ve researched but didn’t find any documentation on whether or how this is possible with RouterOs on a BaseBox2 with a R11e-2HPnD, as I need one combined network where each of the 4 Antennas is able to receive and send as there is a moving client and very high background noise.
Is there a way to archive this with this combination, it should be possible as the Basebox is Capable of MIMO, but
I’m not sure as the antennas are spread over two nics and I didn’t even find a way to do it with one nic so far.

What about the rb600 or rb800 or some boards that are able to carry a daughterboards like rb532 and putting 4 separate radio cards to it?

I don’t want 4 seperate networks, i just need one big network with 4 Antennas in diversity mode.
I also need the ourdoor case.
Doesn’t that work with 2 Network cards and 4 Antenna slots?

You can have one network with 4 cards easily.

One antena for every Rx and Tx. Very good sensitivity.

Thanks for the Suggestion however it is not really the answer i’m looking for.
My problem is that i need 2 120 Degree Panel antennas and one 360 Degree stick-antenna in the 2.4 Ghz Band to cover the complete area. The 4th antenna would be just to fill the port.
The antennas i wanted to use only have one connector for RX/TX, so it would not be possible to use 1 nic per antenna with one connector for each RX/TX too.

The Solution has to be quite portable as it will be used at a racetrack.

So, is it possible to do this with the BaseBox/RouterOs or not? As it is capable of MIMO, this should be the case, but i haven’t found documentation about this.

tldr; Is it possible to Use 4 Antennas in both RX/TX with the Basebox2+with an additional nic?
