Finally figured out our TV system after our DirecTV account was closed after we sold the condo. Tennis Channel in HD became available on DishTV in April so we installed base system at home and also bought a RV mobile Wally receiver and a Vanguard X2 dish for use on the road. After hours of frustration manually aligning elevation, tilt and azimuth on my DirecTV antenna and listening and tuning for the peak signal tone, the X2 aligns itself automatically in a few minutes! Night and day!!!
