OTA connection mystery
I have cable connection from my attic to the living room and two of bedrooms. The other end of three cables were all laying in the attic. I also found a Channel Master tv antenna in the attic which was left by the previous owner. So I figured I would connect them and it will work. I tried connecting the antenna to each of the cable ends one by one and connect the TV to the wall jack in each room. I could get 20 channels in each bedroom but not a single one in the living room which was a bummer.. Then, I thought maybe the cable to the living room is longer and has more loss. So I got a 1-to-4 amplifier/distributor and connected all three to the antenna. Same thing :( bedroom TVs have reception but nothing in the living room TV. Not a single channel. I thought maybe that cable in the attic is not for the living room but to be sure I got a Klein Tools coaxial tester to check the connection. To my amazement it passed! I did some sanity check with the tester in other rooms and everything was fine. I have now become clueless what else I can do.. I wanna know what could have gone wrong. I appreciate it if anyone had a similar experience or have a suggestion. Unfortunately running a new cable would be difficult because of the TV location in the first floor.
