Mystery antenna mount

The paint finish marks it as "Made in USA", I think (coupled with the lack of identification markings), but the "wraparound spring" aerial rod retention method was British/Commonwealth (Aerial Base No.8 and the "Laporte" adapters), later replaced by a screw clamp for Base No.10 and later types.

The spring inside the body that the cable runs through and attaches to the threaded stud makes it somewhat flexible if it needs to bend. It is constructed of all metal.

It's got to be insulated from the vehicle body, and there's a big air-gap where any such insulator (ceramic or rubber) would go - with a curved top surface to allow deflection if it hits something, and the spring would re-centre it afterwards. It's fed from below, so AFV or wireless truck use.

Fitting it would be a matter of taking the nuts off, feeding the threaded rod and cable through the insulator into the vehicle, then fitting a washer and lock nuts to tension the spring (not too much or it'll break contact at the top), then fitting the aerial feeder and another couple of nuts.

That's my guess, anyway.
