Shaw Internet + Satellite connection inside Townhouse ( Install )

So I live in a townhouse ( 1997 built in Surrey, BC ) where I already have Sat connected, the installer had connected it to the cable box outside and each room get their respective signal form the wall outlet Currently, I have telus and since shaw connects via Coax - does that mean the sat connection has to come off? or they use a signal splitter/diplexer even if that then how would the room get connection
