The Antenna System (ANT) from C3S Electronics Development is a Satellite Antenna with linear polarization that has a center frequency of 401 MHz and a bandwidth of 30 MHz. It requires a maximum input power of 3 W and has an antenna main beam gain of 3.8 dBi. This ESA-qualified flight-proven antenna has an input reflection of less than -20 dB and has an electrical power value of 5 W. It has an opening time of 0.1-2.0 s and has an antenna length of 180 mm. It incorporates a curved cross-section tape and produces a near omnidirectional radiation pattern. This V-dipole configurable antenna weighs 150-200 g and measures 100 x 100 x 18 mm with an MCX female connector on the antenna side.
