I have a Winegard satellite dish on my motor home. KVH told me to buy the 211Z receiver which would work with their dish. I bought it and worked for several hours trying to get it to work. I was able to activate the receiver by placing it on my home dish system, but it would not work with the dish in the motor home. I decided to buy the playmaker. I connected it, turned on the TV and it worked without any setup at all. I am very happy.
