A kink might cause a problem that wouldn't show up until later. If the coax is deformed, the center conductor could gradually work its way through the dielectric insulation between the center conductor and the shield to cause a short. This is called "cold flow" and the manufacturer specifies a minimum bending radius for coax to avoid it.

Did you read the Channel Master troubleshooting link I gave you in post #5?

Rather than guess or use a shotgun approach to troubleshooting, I suggest you try to isolate the problem to one part of the system, using the substitution method. The first thing to try would be to replace the coax with a temporary run of known good coax directly from the antenna to a TV through a window or whatever is convenient.

With that test setup you will only have three parts: antenna, coax, and TV. Replace each one with a known good substitute to find out which of the three is defective.
