Radio amateurs Sean Hum VA3SHV and Jeff Nicholls VA3NGJ worked on the
design for a deployable VHF crossed Yagi antenna on the recently launched
NORsat-2.

The very high frequency (VHF) antenna was designed to unfold from the
CubeSat after receiving a command from the Norwegian Space Center to deploy
once in orbit. “This antenna is a completely new type of deployable antenna
— it unfolds to be more than three times as large as the satellite that
took it into orbit,� says Hum. “This is the first time that a deployable
antenna of this type has been contemplated and successfully used as a main
mission antenna for a CubeSat.�

On July 20, cameras on board the CubeSat confirmed the successful
deployment of the antenna.
