> At one time, most QST/handbook designs did have catching zeners on
collectors.
If we are talking about the same thing, where the zeners are, the DC
path to collector, actually there's no RF voltage.
The purpose of those zeners is quite different than SWR protection.

P.S. RF semiconductors are much faster to die than zeners to cut.

breakdown.
