If the TV has HDMI ports, all you need is a $25 Roku box. If the TV has USB ports, you can use a Roku stick.
If you got antenna input too, you have to switch inputs between the streaming box and the antenna from the TV. And you get no on screen menu for the antenna channels.
a Roku TV (TCL brand and others) allow you to change from streaming to antenna from within the internal Roku box. The real advantage of a Roku TV is it will handle your antenna channels pretty nicely. Roku will build an antenna channels menu for you and go out to the internet through the wifi connection to gather info and scheduling for you to see and choose on screen.
