1 Over the range microwaves require a minimum 66 mounting height from floor to top of the micro. 2  The 66 from the floor dimension will allow approximately 13-16 between the cooktop and the bottom front of the microwave.
Microwave energy radiates at wavelengths ranging from 1 millimeter to 1 meter, and frequencies ranging from 300 GHz to 300 MHz. High frequency radio frequency energy is radiated at wavelengths from 10 meters to 100 meters, and frequencies from 30 MHz to 3 MHz.
