1-millimeter band

The 1-millimeter band is a portion of the EHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use. The band is between 241 GHz and 250 GHz. Due to the lack of commercial off the shelf radios, amateurs who operate on the 1 mm band must design and construct their own equipment, and those who do, often attempt to set communication distance records for the band.
