New distance record on the 122GHz band

rsgb | February 21, 2020

Using low power silicon chips with barely a milliwatt, an astonishing new world record of 139km has been achieved on the 122GHz millimetre wave amateur band.

The distance record set in the California mountains is particularly notable as this frequency suffers from severe atmospheric losses due to an oxygen molecular resonance that add to significant conventional free-space path losses.
