About
The UHF Deployable Monopole Antenna is optimized for 360-440 MHz and designed to protect critical TT&C links for smallsats. It features a patented stress-free deployment mechanism that ensures a cleaner mechanical deployment path, reduces the risk of coax damage during motion, and increases confidence in long-term on-orbit performance. This versatile architecture can be manufactured in monopole, dipole, or quadrifilar configurations upon request. It is a flight-ready solution with established space heritage for low-risk, mission-critical TMTC integration, delivering resilient TT&C links for LEO missions. The antenna safeguards the TT&C lifeline with a compact, integration-ready form and a flight-proven, stress-free deployment mechanism engineered for mechanical integrity, resulting in higher deployment confidence and a command link built to stay online.
