What is this ground wire for?

[trikebubble]

I'm in the process of replacing the pos conertone with a decent stereo, and noticed what looks like a un-connected ground wire following an antenna cable up into the roof.
It is the bare braided wire in the photo below. When I removed the concertone it was just hanging there, not attached to anything.
Ignore the attached white lead, I put that on the end to extend it so that once I figure out if it needs to be connected to something, I have the additional run to do so.
Does anyone know what purpose it serves, and where, if anywhere, it should be attached?

Anyone?

Have you tried to pull it out of the ceiling? Any resistance? Maybe a ground for the antenna or a lead to the antenna input for the POS conertone that fell off?

Sounds a AM antenna?

Looks like the ground for the antenna base.
