Does antenna diversity add any value on jamming coverage?

Hello Experts.

We are building a jammer solution on all technologies, for a certain building.
Do we need to implement diversity on our antennas?
I.e. using 2 ports for each technology?

Does the diversity add any value on the jamming coverage?

I would say yes.
Where one antenna port is with min the other antenna port will be with max.

Interesting, never really understood how jammer works.
But I have been told that they are costly if need to cover large bandwidth.

Can you share some details please?
