How do you hook up an n64 with an rfu adapter?

To hook up an N64 with an RFU adapter, first connect the RFU adapter to the back of the N64 where the AV port is located. Next, connect the antenna cable from the RFU adapter to the coaxial input on your TV. Finally, set your TV to the appropriate channel (typically Channel 3 or 4) to display the N64 output. Make sure to power on both the console and the TV to start gaming!
