Axially Fired Apertures 

Tendeg’s axially fired antenna products are used in various applications including feeds for large apertures, directional communication, asset tracking and sensing. 

​

​

  • Composite-Boom-Test.png

    Tendeg has developed a locking motorized clamshell hinge that is at TRL 8 for LEO missions. The hinge uses a COTS motor assembly (vacuum and space rated) for deployment that drives a set of linkages to preload and lock with precision cup-cone interfaces. This provides a highly repeatable deployment and minimizes any bending and torsional stiffness loss through the hinge.​

    ​

    Tendeg has also incorporated thin-walled carbon fiber reinforced polymer (CFRP) tubes to offset feeds and reflectors.  The fiber modulus and resin and the laminate schedule can be tailored to meet low CTE requirements needed for pointing precision.​
