The antenna connects to the tv using the same type of connection as a cable wire, so a usb is not needed. If you are replacing cable with the antenna, you can actually use the cable wiring in your house to connect all of your tv's to one antenna. Put the antenna in the room at the highest point in the house. Get a 2 way cable splitter. One end goes to the tv in that room. The other end connects to the existing cable wire. Follow the existing cable wire to your basement or wherever the cable comes in to the house. Get a 5 way splitter (for up to 4 tv's). Connect the cable coming from the room with the antenna to the input of the 5 way splitter. Connect all of your other tv cables to the outputs of the 5 way splitter. You will then just need to change each tv to use air instead of cable. Be sure to buy quality splitters with gold ends.
