Satellite has deployable VHF crossed Yagi antenna

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.
