I have seen this happen from time to time in the middle of summer. The worst case turned out to be a customer that had painted their antenna black to match their roof.

I have not noticed any performance issues or failures in radio equipment, but but that hot can’t be good for the radios. I would look at finding some way to cover the radio so it isn’t getting direct sunlight on it.
