Product overview
The VLG L1L5 Helical Antenna (D18) is a multi-band active antenna for GPS L1/L5, BDS B1 and GLONASS L1 reception. Its applications span navigation scheduling, tracking and monitoring, and measurement and control. Suitable UAV uses include aerial photography, traffic monitoring and remote telemetry, while additional applications include handheld terminals and high-precision positioning modules. The helical antenna combines right-hand circular polarization with a wide beam pattern and good reception of signals at low elevation angles.
Weighing ≤25 g, the antenna suits equipment with antenna-weight requirements, including drones. It provides 360° omnidirectional horizontal coverage, with passive antenna gain of ≥0 dBi and an axial ratio of ≤3 dB at 90° elevation. Operation requires 3~5 VDC, with current consumption of ≤30 mA and an operating temperature range of -40~+70 °C. The antenna has SMA-J/SMA-K connections, 50 Ω impedance and 50 Ω output impedance, an output VSWR of ≤2, and a noise figure of ≤3.5 dB.
