SDR
Deployable CubeSat antenna module suitable for nanosatellite UHF and VHF communication. Scalable for larger platforms up to 16U.
The SAM (Small Antenna Module) UHF/VHF antenna is ideal for many use cases, such as telemetry, tracking and command, RF, and SDR usage. It accompanies standard Spacemanic features such as I2C and RS485 interfaces, a switch for deployment confirmation, debug LEDs, and more. The antenna subsystem is suitable for 1U-3U nanosatellites and can be scaled up for larger platforms up to 16U.
