Not easy finding all 5 sats for HD viewing. And you'll need a 5 LNB sat. dish to do so (if you subscribe to Directv's HD programming). That dish requires tilt, azemuth and elevation to find all 5 sats. and the mount MUST BE PERFECTLY LEVEL TO START. you'll need a compass and inline sat. finder which screams or clicks (depending on model) when you find a sat. This is misleading cause it will indicate when you find ANY sat., even the non-Directv sats. So, you will have to be pretty close on your compass heading right from the beginning.
