With this receiver when changing channels and using the remote, is it a direct line of site or can this receiver be placed in a cabinet and still be able to change the channels with radio frequency???? I probably sound pretty stupid here but I have nowhere to place the unit as room is very limited. Therefore I wanted to put the unit in a cabinet where it will be out of site. Is it possible with this unit??? I want to get the DishformyRV service and I guess this is the receiver that has to be used with this service. Any and all help would be great.
