RG520F EU " Mikrotik 5G R16" only support 4*4 at lowbands?

Hello!

Mikrotik says that their 5G R16 ( RG520F-EU ) supports 4x4 mimo at lowbands such as B8, B20, B28 and n28 and only 2x2 mimo at B3, B8, n78?

Is it true?

Dear @SELBERG
Actually, for router, it depends on router manufacture.
You should confirm with them.
