Are we speaking of the same types of applications? The radar in a Phantom F4J / S used
wave guide both on the transmit and receive side.

Btw, it is not pretty if you lose pressurization at altitude while radiating and don't
forget to change the desiccant / dehydrator.

Probably not. I built radios, 50W max.

Without a drawing showing dimensions and tolerances it is impossible
to answer this question, since the required geometry and tolerances
determine the process. Consider the tolerances on a shaft as being .
0001" or .008" on diameter. It does affect the choice of machining
process, right?
