R52HN J4 and J5 what frequency??

I bought a new R52Hn card. It says dual band..does it mean I can configure 2.4Ghz for J4 and 5.8G for J5?
Or both connectors can be set to 2.4G or 5.8G. If this is the case then, I can use this card for a dual Pol antenna..is it right??

Thanks

it is not the case, you can change between 2.4 and 5 GHz band as this is MIMO card. But you can use d-pol antenna as both chains of card transmit (if configured that way)
