You do not want to keep pressing the button on your RF modulator. Therefore, when shopping consider an RF modulator that comes with a remote control. However, this should not stop you from purchasing a good model if you find one.

Set Up

Consider an RF modulator that’s quick and fast to set up. You do not need a unit that you’ll have to spend hours making connections. While on that, ensure that there’s an instruction manual in the package.

HD Input
