I attempted to get an install but LOS was an issue unless the one of the dishes was placed on the front of my house (wife no-go). The installer was going to use 2 dish 500s. Could I use a 1000.4 in Albany, NY. The installer thought no as I would lose 2 sd locals that do not have an HD feed. My set up was to be 2 722s feeding 4 tvs. Any help would be appreciated, thanks.
