Vodafone B2000 LTE Router SMA connections

Hi

I want to upgrade to the Vodafone B2000 LTE Router.

I am in a rural area so I would use the SMA antenna connection for attaching to my external antenna which is on a mast.

I read that the Vodafone B2000 LTE Router has 2 SMA connections, and I need to be able to also send the WiFi signal down to my house which is 30m away from my office.

Does the other SMA external connection on the router enable one to send the WiFi signal out? IE is the one SMA connection for incoming and the other one for outgoing?

Thanks,
Brendon
