Ethernet Switch with Roamio Base

I'm fairly new to Tivo and still learning some things. I have a question. I currently have a Roamio Base and a Mini connected via MoCA... I used two MoCA adaptors: one at my modem/router to create my MoCA network and another is connected to my Roamio Base to bridge the connection. The adaptors I use ( Actiontech ECB2500C) only have one ethernet out port....my problem is at the location of my Roamio Base I need an extra ethernet connection for my Apple TV.....my question is can I buy and use an Ethernet Switch (hub) and connect the ethernet cable from my actiontech adaptor to the switch then use the ethernet switch's ports to go to my Roamio Base and Apple TV or will that setup not be compatible? I know I could buy the actiontech ECB3500T which has four ethernet ports but thats more expensive than buying a switch.....any input is appreciated..thanks!
