DarwinFPV Quantum 5.8GHz - 65mm RHCP SMA

DarwinFPV Quantum is a short omnidirectional antenna with RHCP polarization and a straight SMA connector for the 5.0-6.2GHz band. With a total length of 65mm and a weight of 7.3g, it is suitable for the video transmitter of smaller drones, cinewhoops, as well as 5" freestyle and racing quads. Thanks to its compact dimensions, it is also suitable for the receiver side of FPV goggles. RHCP polarization is suitable for analog video transmission or HDZero.

The radiating element is made of a gold-plated PCB. PCB manufacturing ensures small differences in characteristics between individual units, and the gold plating protects the radiating element from oxidation, so the antenna retains the same parameters even after prolonged use. The wide 5.0-6.2GHz band covers all common FPV channels and allows the antenna to be used with transmitters at lower and higher frequencies (X-Band, L-Band). The antenna radiates evenly in all directions in the horizontal plane, maintaining a stable image during rolls, turns, and sideways flight. The manufacturer specifies VSWR ≤1.3 — a low value means that most of the power is transferred from the transmitter to the antenna, with only a small portion reflected back.

The 15mm diameter head is protected by a PC+ABS cover that withstands hard crashes without cracking and protects the radiating element inside.
