Quadrifilar Helical Antenna Product Introduction:
The RAT-830S adopts a four-arm helical structure design. Compared with traditional antennas, it has superior gain performance and wide-angle circular polarization characteristics, enabling it to receive more low-tilt satellite signals. It is particularly suitable for terminal products such as unmanned aerial vehicles, handheld devices, and wearable devices. It supports simultaneous transmission of DC bias and RF signals through a single SMA interface. All antennas have undergone 100% RF testing.
