What model of satellite should I add to my NETGEAR Orbi Home Mesh WiFi System (RBK50) to get more coverage

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.

Keeping with an RBS50 would be recommended if needed...
