The QHA from Helical Communication Technologies is a Satellite Antenna with a frequency range of 400 MHz or 437MHz. This antenna gain of 3.5 dBi and a -3dB beamwidth of 120 degrees. It has an axial ratio of less than 2 dB and a VSWR of 1.5:1. The antenna has a transmit power of 10 W and requires supply voltages of 5, 12, 24, or 28 V DC. It has a mass of less than 180 g and measures 100 x 100 mm (depth x width), 40 mm (stowed height), 270 mm (400 MHz deployed height), and 260 mm (437 MHz deployed height). The antenna filars are constructed from super-elastic Shape Memory Alloy materials. It is designed for ground-based and space-based communication with satellites placed in low earth orbit and deep space.
