Kev, any idea what year yours is. The one I have is early--probably off a 51 and believe the one being worked on is too.
There appear to be several changes between the two. Maybe for a reason because of problems? There was a service article or two early on about sending non working antennas back to the factory for credit. Must have been a problem because there was another a bit later saying too many antennas returned were unrepairable because of damage. Had instructions on how to collapse or remove the mast from non working antennas so they could be shipped. Any coming back from then on with broken or bent masts would not get credit.
The noise or arc supressor capacitor is probably minor but a bigger change is the brush screwing directly to ground on yours instead of being connected to a terminal. Mine has ground being made by a copper strip connected to a terminal under the fiber and squished or otherwise making contact with the case. It also has a contact between which appears to be a circuit breaker affair. If 51Packard's is the same, seeing both were eliminated on later antennas, either might be a good place to concentrate.
