What is the SHF frequency range?

Explanation:
SHF, or Super High Frequency, is the microwave band used for radar and satellite links. It spans about 3 GHz to 30 GHz, sitting above UHF and below EHF. In wavelength terms, 3 GHz is roughly 10 cm and 30 GHz is about 1 cm, which explains why SHF supports compact, high-directionality systems. Therefore, the SHF range is 3-30 GHz. Other options fall outside this band: one is in the megahertz range, another sits in the UHF range, and another lies in the higher-frequency EHF region.
