Or for $30 you can get one of these. Plug in a USB stick or HDD and you have a no-subscription DVR. It will pass the signal to your TV so can record one channel and watch another one (using your TV’s tuner, as long as it has a digital tuner) at the same time, and it records in full HD with a HDMI port so you can watch your recordings in hi-def.
Also, assuming you have a digital TV with an ATSC tuner, as all new TVs are required to have, it won’t hurt to get a cheapish pair of rabbit ears and see what you can tune in. I live in Tucson and get a total of 21 channels. Five of them are Spanish-language, but the other 16 hold my interest. All of them come in super strong and clear, even the one 45 miles away from me and have awesome stereo audio as well.
I can receive ABC, NBC, CBS, PBS, and the CW.
Cozi TV, Antenna TV, and MeTV - all retro channels.
Grit, This TV, and getTV - all classic movies.
Ion TV - mostly dramas like Blue Bloods, Criminal Minds, and The Ghost Whisperer.
Laff, which has comedy movies and sitcoms.
Escape, which is mostly crime shows like Forensic Files, FBI Files, and Unsolved Mysteries and crime thriller movies.
I get all of this with an indoor antenna on top of my TV set.
