I'm not exactly sure where to post this but I recently moved into a new place and each bedroom has a coax and phone wall plate.
There's a photo of the wall plate. I know the top coax connection is for cable, the top rj-11 is for phone, and the bottom rj-45 is cat5e, .... But what is the bottom coax for that is labeled "BF" ?
All of the wall plates in all rooms have this.
Thanks for the help!
