Query: Dead Out of the Box

I replaced a Terk antenna that had been working well for about 3 years but crapped out. My replacement antenna that was to fix the system did not work any better. The XM radio did not recognize an antenna was plugged in. I replaced it temporarily with my car antenna and it worked fine. The new antenna was bad out of the box. Unfortunately I discarded the invoice assuming the new antenna would work so I couldn't send it back. Evidently these antennas either work well or don't work at all.
