I once had a job servicing microwave repeater station. About 1000 ft up on the tower are reflectors/antenna they have heaters that came on at 40 degrees F. Heaters stayed on until about minus 18 degrees F then heaters turned off. When it gets cold enough all humidity in the air freezes then it is not possible to have frost with no humidity. I can't remember what negative temperature frost can not form I am thinking -18 degree F but not sure that is correct?
I did online search & not finding the answer probably because I am probably not asking the search question with the correct words. This condition probably has a special name that I don't know.
