Is there an RF Frequency remote that will work with a Dish Network V211Z receiver. This is located in a motor home and I don't have "line of sight" between the TV location and the receiver
You will get a better answer in the dish network forums instead of general satellite.
However, I believe the 211Z remote is IR only. I think you would need to purchase one of the many aftermarket IR extender products that relay ir signals over a wire or wirelessly. Find them on Amazon or eBay
