Millimetre Waves is one of the many areas where amateurs innovate. The short wavelengths lend themselves to portable equipment and high antenna gains to achieve remarkable operating ranges. The 76GHz band is available to all UK Intermediate and Full Licensees. In the UK narrowband operation is centred on 75976 MHz within the UK Amateur Primary segment.

The UKuG 76GHz loan system enables you to get a taster of modern narrowband DX on 76 GHz. The hardware was the original creation of the late John Wood G4EAT from Danbury in Essex, one of the leading UK operators, who sadly became a SK in Feb-2015.
