In addition to satellite dishes, the
FCC rules prohibit covenants from preventing a homeowner from mounting an over the air television antenna on their roof provided that it is the only location for receiving an acceptable quality signal.
The reason for these rules is that the television broadcast stations are part of the our national Emergency Alert System (formerly called Emergency Broadcast System).
But as Handie has pointed out, reception is generally poor in these areas. But the equivalent Comcast Basic Service is probably only around $15-20/mo.
