hAP ac 3 remote/extend antenna connections

Hi - Is it possible to extend where the external antennas go for the hAP ac 3?

The router is installed inside a closet with metal racks, can we use a cable and install the antennas outside the closet?

If so, what is the connector needed for both ends please.

Thanks.

You have to use pigtail or cable with smar + your antena conector (N-male usually).
