Once you have the receiver connected to the Winegard you will go to Menu, Settings, Satellite, Repeat Satellite Setup. You will see the antenna and switch settings. You want to set the Antenna to 18" round and the Switch Type to Multiswitch. If it is a DVR you will also need to change it to Single Tuner unless you can get that 2nd coax run into the RV. You may have to turn on the antenna and let it lock on to complete the setup but you do want to go all the way through the end of the setup routine to get the settings to "stick".
