When I put in my new deck I forgot to connect the antenna wire, so I had zero radio. I have recently gone back in and connected it, I didnt have any wire nuts so I entertwined the wires, folded it back and taped it with electrical tape. My antenna works (goes up and down) and I get most channels, but very faintly. The signal waivers, it will be loud, then soft, then loud then static. Anyone know what's wrong?
