DarwinFPV Quantum 5.8GHz - 150mm RHCP SMA

DarwinFPV Quantum is an omnidirectional antenna with RHCP polarization, an SMA connector, and a total length of 150mm for the 5.0-6.2GHz band. Thanks to its length, the radiating element is positioned above the battery and other drone parts that would otherwise obstruct the signal, making the antenna suitable for the video transmitter of freestyle and long-range drones with frames from 5". RHCP polarization is suitable for analog video transmission or HDZero.

The radiating element is made of a gold-plated PCB, which is manufacturing-standardized, ensuring minimal variation in parameters between individual units. The gold plating resists oxidation and reduces signal loss. The antenna covers the entire 5.0-6.2GHz range, covering all commonly used FPV channels, with the best performance in the 5.6-5.8GHz band. The manufacturer measured it in an anechoic chamber: it radiates evenly in all directions in the horizontal plane, and the maximum measured radiation efficiency is 60.18 %. Higher efficiency means more transmitter power is radiated and less is converted into heat.

The antenna head has a diameter of 15mm and a housing made from durable PC+ABS, which protects the radiating element during crashes. The antenna screws directly onto the SMA connector of the video transmitter or onto a pigtail.
