What is the ruling on watching only news and religious channels via a satellite dish after deleting the rest of the channels that violate Islamic law?

Television and satellite dishes are two means that can be used for good or for evil. If you are certain of your ability and your family's ability to use them only for good and permissible purposes, then there is no harm in acquiring them, despite the difficulty of guaranteeing complete safety from any transgression. However, if you fear weakness and inability to control them, then safety is better.
