The FTM's go on each of the two inputs for HR20. Currently these are not being used by DirecTV, but in the future will enable you to run one line to your DVR instead of two.
The Slimline is a lot easier than the original MPEG-4 dish, the AT9, and the allginment process is nearly identical. We have a
video on the installation, if you want to see what your getting into. The biggest difference between the older DTV dishes and the 5 LNBS is that a meter is absolutely required. Most of our customers are just buying the
Accutrac Pro and doing themselves. One thing that a lot of people seem to over look is making sure the mast is perpendicular, it if is not, all other adjustments are off. There is a bubble level in side the mast so it's not that hard.
