This certainly is not a "raw to finished goods" plant, it's a typical Musk exaggeration.
The housing, maybe. Makes sense to produce that domestically at the volume SpaceX requires, less shipping costs because the dishes do take up volume.
But the PCB? Almost certainly not. With any luck they're making and assembling the PCB in house, but the components originate from a lot of suppliers and there are a lot of components on it [1]. Personally, I'd guess the latter, given that the PCB contains a lot of pretty novel tech [2] of which I'm certain that SpaceX wants to be able to iterate on as fast as they can, without having to wait for even a day or two for a new plane full of PCBs from China.
Regarding components, it's not like they are making chips in the same plant as a laptop plant in China either, are they?
I guess the question is which components function or cost benefit the most from tighter coupling, and which components (eg antenna) do you isolate to keep your secret sauce internally controlled.
