Hello,newbie here so be gental.Im having an issue with our dish reciever.Im using this reciever in the home and our r.v.It works perfect in the home but when I install in the R.V. we only get a small number of channels,and when we do get them it takes a couple of mins.for them to come up on the screen. I have Winegard Satelite model # rm-9946 single LBN.Owner before me said he never had this issue,can anyone help me with this issue?
