I get a great TV signal by touching the center wire of a coaxial cable to the threads of the wall connection.
If I screw on the cable properly, there is no signal.
What's happening and how do I fix it?
Will reversing the wires on the television antenna fix it? I didn't think that antennas had any polarity, but that seems to be the problem.
P.S. Another problem is that I can't find the antenna, because it's a new house. I think it might be inside a wall or attic of finished garage. If I can fix it with cabling alone, that would be great.
