[Milsurplus] ARB Antenna capacitor

[W2HX]

I have an ARC-2 radio with a doorknob cap in series with the antenna post (outboard). I think it is to help tune 50 ohm antenna. Do you know what the radio is expecting for impedance on the ARB antenna connector? Could that be its purpose?

Which is fair condition ARB with local tuning crank, with spinner post broken off. 
But what interests me is the large mica cap attached where the antenna connector should be. 
In  the past I have seen one out here on the opposite coast with exactly the same type capacitor in the same position. So was this in place merely to replace a broken-off antenna connector, or is there some more arcane purpose to it?
