When you say "additional receiver", I assume you mean receiver and
antenna both?


Yes. Since the boat is some 50 miles away from home, a second dish is
pretty much a requirement. The cost of the hardware (specially the dish
antennas) is chump change. The cost of the service is directly proportional
to the number of premium channels you subscribe to, just like with cable.
If you are considering the move to a satellite service, by all means get a
receiver with a built-in digital video recorder (same concept as TIVO). I
can tell you that it will absolutely change the way you think about, plan
for, and ultimately watch TV, and all for the better. The nice part of
having the DVR incorporated with the sat receiver is it cuts down on space
requirements and cabling, and you use the native guide for selecting
recording events. Way cool.
