DirecTV installers do use grounding blocks, but don't recommend true surge
suppressors, apparently because most readily available ones aren't rated for
their HD service and will decrease HD signal levels. There are lengthy,
useless posts on several DirecTV and DBS forums on the topic.
You need a surge suppressor rated to at least 2.5 GHz with DC pass for the
HD dish feed lines. Most "satellite" surge suppressors are only rated to
1.5 GHz, which is OK for Dish Network systems, but not DirecTV. Monster
(and others) have in-home protection centers that spec OK, are very
expensive -- but who wants the lightning surge suppressor in the living room
plugged into the wall outlet for a ground?
