Hello my new trailer has a weingard auto satellite antenna. I have direct tv at my house. I have no idea how to proceed to get a box hooked up for the trailer. Is it as easy as just hooking it up and turning on the switch. There is a switch in the bedroom that I surmise may be the antenna. I switched it on and heard something moving above me?? Id be willing to pay for some help or I can take it to someplace to get it up and running. I’m in El Cajon. Thanks. Ty.
