About

The Antenna Reflector Hold-down Lock (mechanical) Type 2 is a critical component of an antenna hold-down system, engineered to keep antenna reflectors securely stowed. Released in 2016, this mechanism offers a guaranteed service life of 6 years and is designed for an operational life of at least 50 actuations. It can withstand ultimate side loads of 200 kg at the interface surface with the reflector and operates effectively across a wide temperature range from -100 °C to +100 °C. With a mass of 0.37 kg, it provides a robust clamping force of 400 kg, ensuring the antenna remains in its stowed configuration until deployment is required. The estimated production and delivery time for this component is 4 months.
