i know what it is
I work with these. They are intended for military use mainly. They are a type of directional antenna used for detecting where a radar lock is coming from. Four of them are generally used on a vehicle, mainly aircraft. They are placed in each of the four corners. Civilian use could range from simple radar detector antennas to detecting where a source of rf interference in the radar bands are coming from.

Tests as diode
It's a wideband microwave spiral antenna, with a diode in the center, and uni-directional via the resonant cavity behind. For lots of info goog: spiral antenna

It's probably a military microwave detector. Could be comms. Or, whenever you're being 'painted' by EM beams, time to duck.

What's all the fuss?
This is just an ordinary flux capacitor...

A customer from fishers,in
i suspect its a pressure transducer, if it was a heater device the black part on top wouldnt be needed.

Possible Use?
It looks like a cigarette lighter - the type that is found in a car that heats up in the 12v plug, then the coil gets red hot when electricity is applied to light the cigarette.
