Hello, I have an indoor flat antenna that's struggling to get certain channels; it's mainly ABC and FOX that are spotty and often get lost. However, their signal becomes significantly better if I try and move the cable a little bit or even just touch it, and in many cases I've been able to resolve my issues by adjusting the cable without moving the antenna, but it never seems to be a permanent fix. I've read here that problems like this are often a fault of the cable itself, not the antenna, and that one solution would be to replace the coax cable. My problem is that the cable is physically attached to the antenna, and I probably wouldn't be able to remove it without taking apart the antenna. I was wondering if something like this would be possible to replace it. Also, the antenna needs to be plugged in and splits into a USB cable and a coax cable at the TV end, would that cause any issues for replacing the coax?
