Key Takeaways. Radar works on the principle of electromagnetic waves. S-band radar utilizes the microwave band in the electromagnetic spectrum, which ranges from 2GHz to 4GHz. The most notable advantage of S-band radar is it is less susceptible to atmospheric attenuation .
Read moreWhat is the difference between S band and C band?
It is not uncommon for a S band dish to exceed 25 feet in size. C band radars operate on a wavelength of 4-8 cm and a frequency of 4-8 GHz . Because of the wavelength and frequency, the dish size does not need to be very large. This makes C band radars affordable for TV stations.

WMO is concerned about this as the use of the 2.7–2.9 GHz frequency (S-band) by meteorological radars is critical for weather monitoring and prediction applications.
