I have a slimline 5 LNB multi-sat direct tv dish. I travel in a R.V. so I get to align the dish alot. Been using the receiver and 101 to get alignment but not getting all the channels especially HD. After reading some posts, it appears that I need more equipment to properly align the unit. It appears that a ASL-1 and some kind of 18 volt meter is needed. Could somone please give me some direction?
