Cutting the cable, lets talk options and media setups

Interesting.
I'm wondering if there's something interfering with your reception in that part of your apartment where your bedroom is located? Those antenas can be very finicky.
Also, have you tried doing another channel scan on your t.v in the bedroom? I had to do that on my t.v downstairs after I repositioned my antenna. I too, also received several stations I didn't before I did the re-scan.

I'm almost afraid to and lose everything lol.

I would almost think that there is something in the wall between the two rooms that, along with the metal blinds are causing the weak signal. I won't complain too much since the other TV is going smoothly. The bedroom has the Fire Stick with KODI, so i should be good moving forward.
