Moved into a house that has a Hughes satellite dish mounted near the roof
line. The house is wired for both satellite and cable. I've opted for
cable for now. However, I'm curious to know if I could use the existing
satellite dish (in conjunction with a tuner) as an antenna to pick up local
TV stations.

In my area, Time Warner Cable is not permitted to carry the HD signals of
the Sinclair Broadcasting FOX and ABC affiliates. I'm frustrated by the
limited HD options and would like to purchase a tuner to use with my Sony
projection system. The projection system is located in the basement of the
house and I would have very easy access to the coax going to the dish.
Mounting an actual antenna outside would require a bit of additional effort.
Any advice appreciated. Thanks.
