via the RSGB: Australians set new microwave records

The Wireless Institute of Australia (WIA) reports that new records have been set on the 47GHz and 122GHz bands.

Operating 47GHz mobile, David, VK5KK and Wayne, VK5APN set a new record of 20.8km on 11 March 2019.

At 122GHz, Matt, VK2DAG and David, VK2JDS set a new VK2 state record of 100m.

Although this is some way short of the world record, the 122GHz band is fiendishly difficult and has serious attenuation challenges due to an atmospheric oxygen resonance.
