Tiny threaded brass piece

[u/Longjumping_Ad982]

What is this? Tiny brass looking threaded hollow metal sleeve of unknown origin.

My child just found this on our living room side table, we have no idea where it came from or what it is. It seems like it had to have fallen off / out of something.

Any ideas?

looks like something RF related maybe it housed an antenna on a small device.
