So I looked into an antenna for my house and found a bunch of cables downstairs leading to different parts of the house - outside, up through the floor to extend to the three seasons room, up in the attic and into the bedrooms. Then, when my dad and I were putting up some lights so we could see in the attic at our main staircase and in my wife’s closet and we found an antenna set up with a cable connected in the attic and on the east side of the house. We found the cable that hooked up to the TVs, an input and output box in the basement and some cables with a tag that said “ANT” on it. Once those were plugged in, the tv found all of the channels through the air, including CHSN. It was pretty sweet that we had an antenna all set up just sitting there in the attic. Good thing the previous owner didn’t have it taken down when they got Direct TV and then Comcast.
