I found this in a box. Can someone tell me what it is? It has 3 pins in the connector. There is no marking on the body.
Thanks!

It is NOT an antenna, that is a multi-pin connector at the bottom, and the flat section at the top appears to be soldered on.Might be some kind of UHF antenna. The coloured blob might indicate the frequency or channel. Need to see the pins in the connector and resistance measurements between them.
OK, if the disc is a piezoelectric material then it is some sort of microphone or acoustic pickup, or possibly a sound generator. I have some SHURE brand microphones of about those lengths, but they look much different.Thank you all for the replies. Here is the picture of the connector. The words at the bottom are "Chicago USA" and "Amphenol", the latter is a large maker of electrical connectors. The tube seems to be made of brass. It comes with two lengths. This one is about 6" and the other 23". The disk has the color and texture of a piezoelectric buzzer.
