Since I quit satellite I am finding the mounting arms and cables are quite useful in other ways. Again, make sure you do not have any satellite splitters or switches in the cable if you use it for an antenna run.
My cables work fine for Comcast/Xfinity and also for my Antenna that I use for backup.
My mounting arm that I used for my Directv slimline is now holding my Ambient weather station along with my Televes Diganova Antenna. I pitched a couple of the dish mounting arms that I wish I had kept to help friends mount their small OTA antennas.
