RB4011iGS+5HacQ2HnD custom/longer antenna

Hey, I’m wondering if it’s possible to add an different antenna to the RB4011iGS+5HacQ2HnD. Unfortunatelly it ended up in a place where it’s hidden in a closet so I’d like to extend the antenna and put it out of closet.
Does it even make sense? Will I loose some signal strength if the antenna cable is long e.g. 2m?

If it’s possible, could you suggest which antenna would be good for that?

Thanks

Sorry for the late reply, but as you probably found out by now, they are sadly not user replaceable. And probably not worth the risk, since any AP can be used from a LAN port.
