The AQHA.11 GNSS quadrifilar helix antenna is a high-performance GNSS (global navigation satellite system) L1 antenna for demanding GPS / GLONASS / BeiDou / Galileo applications. Its wide bandwidth allows maximum coverage of the main global satellite constellations.
The wide axial ratio beamwidth of the quad-helix provides excellent reception and signal fidelity across the sky, reducing multipath effects while ‘seeing’ more low-elevation satellites compared to patch antenna designs. These characteristics make it well suited to timing, precision positioning, telematics and autonomous routing applications.
The AQHA.11 is provided with a dual-stage combined front-end, which provides high rejection, low noise figure and excellent gain. The amplifiers accept a wide input voltage range of 2 V to 24 V and require low current (10 mA typical). The quad-helix AQHA.11 is ready for outdoor industrial and commercial usage with full -40°C to +85°C temperature rating and IP67 ingress protection rating.
