I’m original owner, on the plate that the switch is mounted on one side says antenna and the other side says cable. When in the rv park and I want to watch their cable I push the rocket switch down on the side that says cable ,when I want to watch over the air tv I push the rocker switch down on the side that says antenna and I get over the air tv. Worked great for the last 12 years . Then last month switch didn’t work any more. Multimeter showed no power to switch . I have satellite tv so no big deal, but I like things to work whether I use them or not .
