I'm looking for service in Brookville PA for DirecTV Stream

My sister-in-law visited us here in Milton GA, and was acclimated to our DirecTV Stream app that we use.  She would like to know if DirecTV Stream is available in Brookville PA 15825, including the local stations there.  She currently has Comcast Xfinity for her cable and internet provider, but would like to drop the Xfinity TV service and only have Comcast for her internet service for using DirecTV Stream.  Please have a DirecTV Stream employee respond to this post.  Thank you very much in advance for your prompt response.
