Had it previously been working and then quit? Or, are you new to this RV and trying to get it to work?
You need to be careful and make sure the amplifier in the switch for the antenna is working. Second, if you have an older RV the tv may require a digital tv converter to tune in over the air channels. Rv tv's started the digital tuner installs around 2008 or so. You need to be careful where you install the converter boxes if they are needed in combination with the switch. For satellite, it depends greatly on the sat receiver whether or not you can use the switch at all. Many sat receivers will need to be installed with other than coax connections directly to the tv.
Good luck-- Mick
