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.

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

Hmmm... Hot surface Igniter for pressurised gas ?
maybe it is used for igniting fuel gas when i look at it though it seems to look like some type of rf device like a transducer of some sort or an rf antenna for line of sight or sensor head who knows ... lol would be fun for experimenting .

Mystery Component
Does look like a heater of some sort, but why would it have polarity markings?

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.
