I figured out that one of the coax cables where the TV will go go upstairs into a closet upstairs, which is good because I wanted to put an OTA antenna upstairs. However, the place I wanted to do it required connecting about 4 different coax cables to get it into the room I want to put the antenna in. When I tested it, it didn't work (might have linked the wrong cables), however, when I attached the antenna half way through the links, I only got 10% reception.
That being said, does length affect the signal greatly? Does the amount of connections affect the signal greatly?
