Compatible with the 211 receiver, but maybe not able to find the Dish satellites reliably. I got rid of my Trakvision SF back in 2008 cause it was difficult to get locked onto the right satellite. That was Direct TV rather than Dish, but both have changed their satellite configuration multiple times since the LF/SF domes were designed. An auto-seeking dome depends on being able to find the right satellite among several up there, and the SF isn't too clever at that. Newer models have more sophisticated capabilities that identify the right "bird" every time. With my old SF, it was hit or miss and very frustrating.
So yes, it will work, but you may not like getting it tuned in very much.
