The EnduroSat UHF Antenna is a low-profile, compact and lightweight solution with circular polarization. Its radiation rods feature a triple redundancy deployment mechanism. The UHF Antenna is designed to be mounted on the Z side of a CubeSat structure according to the CubeSat standard and is compatible with EnduroSat's 1U Solar Panel Z. The antenna can be deployed by EnduroSat's UHF Transceiver or OBC (Onboard Computer).

The deployment mechanism uses burn resistors to melt a burn wire and release the doors holding the antenna rods. Each rod can be deployed using two independent burn resistors for redundancy. They are controlled via I2C or digital input. The additional direct control feature enables activation of the entire burn resistor chain. Deployment status feedback information can be collected through the I2C interface pins on the connector.

To avoid significant voltage drop, the length of cables should be kept minimized. The recommended cable is AWG 24.
