As an update, I emailed Winegard support and described my issue. They said it was not a warranty issue as I must have damaged it somehow. I explained that the only thing that could have caused this problem was my ADCO cover and northern IN snowfall. They did tell me the part number of the cable. However, I can't figure out how to get the roofside end of the cable unhooked. It is covered with copius amounts of caulk. After trying to dig it out, it doesn't look like a coax connector at all, rather it appears the wire travels into the roof. I'm still planning on crimping a male and female connector to the two end of the coax and cover with the rubber boot and caulk. The coaxial cable is a different size, so RG6/U connectors are out of the question. I'll talk to local electrical supply stores and try to get the connectors there.
