About

FPV & RC Antennas Antennas are one of the most critical components in any FPV drone or RC aircraft system. The right antenna determines your video link quality, control range, and signal reliability — whether you're flying proximity freestyle, long-range FPV, or racing on a tight track. At Unmanned Tech, we stock a comprehensive range of antennas for video transmission, control links, GPS, and diversity receiver systems. Types of FPV & RC Antennas Video Transmitter (VTX) Antennas – Mounted on the drone, these transmit your FPV camera feed to your goggles or monitor. Available in linear (dipole) and circular polarised (RHCP/LHCP) variants. Circular polarised antennas significantly reduce multipath interference and are the preferred choice for most FPV pilots. Video Receiver (VRX) Antennas – Fitted to FPV goggles or ground station receivers. Patch and helical antennas offer high directional gain for long-range flying; omni antennas suit proximity and racing. Diversity Antennas – Used in diversity receiver systems that automatically switch between two antennas to maintain the strongest signal. Typically paired as one omni + one directional antenna. Control Link Antennas – For RC transmitters and receivers operating on 2.4GHz, 900MHz, or 868MHz. Critical for maintaining a reliable control link at range. GPS Antennas – Ceramic patch antennas used with flight controller GPS modules for accurate positioning, return-to-home, and autonomous flight. Long-Range Antennas – High-gain directional antennas (patch, helical, Yagi) for extended range FPV and ground station setups. Key Antenna Specifications Explained Frequency – Must match your system. FPV video typically runs on 5.8GHz; control links on 2.4GHz, 900MHz, or 868MHz (ExpressLRS, Crossfire, ELRS). Polarisation – RHCP (Right Hand Circular Polarised) and LHCP (Left Hand Circular Polarised) antennas must be matched between TX and RX for best performance. Mixing polarisations causes significant signal loss. Gain (dBi
