The Kerbalism Antenna module does not have a max pressure/Q value which results in antennas being indestructible to aero forces unlike stock, removing some of the balance between fixed and deployable antennas
You are right. That is a consequence of the use of ModuleAnimation, instead of ModuleDeployable. Apparently, the atmosphere breaking is implemented by the latter.
