We are trying to hook our dish 500 system to our camper. We had it up but was only picking up half the channels so we thought we would move it. We have a 311 receiver and dish pro lnb. We have a sw21 switch. We are picking up 110 with signal but we cant pick up 119. If we do pick up a signal from 119, it is picking up 110 and says wrong satellite. We also seperated the lnbs by removing the switch and connecting each lnb directly to the receiver and we still get 110 on either lnb. Does anyone have an idea what may be causing this?
