1.2-centimeter band
The 1.2-centimeter or 24 GHz band is a portion of the SHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use. The amateur radio band is between 24.00 GHz and 24.25 GHz, and the amateur satellite band is between 24.00 GHz and 24.05 GHz. Amateurs operate on a primary basis between 24.00 GHz and 24.05 GHz and on a secondary basis in the rest of the band. Amateur stations must accept harmful interference from ISM users. The allocations are the same in all three ITU regions.[1]
