Eh. I knew a physics professor once who had a story about a charismatic preacher who unloaded a revolver into a telescope mirror for being a violation of God's domain, and they just put a little black paint around the holes and returned the mirror to service with no meaningful degradation to its imaging capability. I'd expect a small hole in a big radio-collecting dish to behave more or less likewise.
