Not sure that I agree with this.  The little DSS dishes are pretty easy to 
align compared to a big dish pointed at a KU sat, at least with respect to 
finding the signal.  A big dish pointed at a KU sat only needs to be off the 
sat by less than a degree, and you will have lost the signal, while a small 
dish can be off by several degrees and still receive a reasonably strong 
signal.
