At a park this weekend that has cable. On antenna, all TV's work fine. On cable, bedroom TV great picture, living room has a decent, somewhat grainy picture and no picture outside. Switched out splitter in living room, helped living room picture some, still no picture outside. Next I ran a cable from feed at bedroom TV to splitter in living room. Good improvement to living room TV, still no picture outside. Ran the cable from bedroom to outside TV, great picture. Ran a different cable from splitter in living room to outside TV, received same channels as living room TV, but all very fuzzy.
With the outside TV getting a good picture on antenna, but not cable, is it possible for the cable from inside splitter in living room to outside TV to be bad? I guess I don't understand how the cable can be good for antenna but not cable. Also wondering if the main problem could be between bedroom and living room as the picture degrades from there and gets worse to outside. But again, why is the antenna good and the cable pic not?
