Multi-Frequency Drone GNSS Antenna | GPS L1/L2 · BDS B1/B2/B3 · GLONASS G1/G2 · Galileo E1 | IP67 | Ultra-Compact Φ27.5mm | SMA Mount | Lightweight UAV · Agriculture · Telemetry · Patrol.
The EV210 Multi-Frequency Drone Antenna is an ultra-compact, four-system GNSS antenna engineered for the weight-sensitive, space-constrained integration requirements of lightweight UAV platforms and precision drone systems. Supporting GPS L1/L2, BeiDou B1/B2/B3 — including the globally networked B3 frequency for enhanced positioning stability — GLONASS G1/G2, and Galileo E1, the EV210 delivers broad multi-constellation GNSS coverage that maximizes satellite availability, improves positioning geometry, and provides the signal redundancy essential for reliable autonomous drone operations across all geographic regions.
The EV210’s ultra-compact Φ27.5 × 57.6mm cylindrical form factor and SMA male connector make it directly compatible with the GNSS ports of the most widely deployed lightweight drone autopilots, navigation modules, and survey UAV flight controllers — providing a plug-and-play multi-frequency antenna upgrade for platforms where the standard single-frequency GPS antenna limits positioning performance. The rubber pad base provides vibration damping and a secure non-slip contact surface that protects the antenna and drone airframe during the continuous vibration exposure of agricultural spray drone operations and low-altitude inspection flights.
With an exceptionally low noise figure of 1.3dB or less and LNA gain of 33±2dB, the EV210 delivers clean, amplified GNSS signals across all supported frequency bands with minimal added noise — directly improving receiver sensitivity, satellite acquisition speed, and carrier phase measurement quality for centimeter-level RTK positioning. The EV210’s high out-of-band rejection suppresses interference from 4G/LTE cellular infrastructure, video transmission systems, telemetry radios, and power line electromagnetic emissions — maintaining stable GNSS lock in the electromagnetically complex environments where traffic patrol, power line inspection, and public security monitoring drones operate.
IP67 waterproof rating after mounting — with IP65 standalone protection — ensures the EV210 withstands agricultural spray drift, rain, dust, and field humidity encountered during daily commercial drone operations. Operating from -40°C to +70°C, the EV210 covers the full range of agricultural, inspection, and surveillance drone deployment environments from cold-climate crop monitoring through tropical disaster response operations.

Technical Features — Detailed
Ultra-Compact Design for Lightweight UAV Integration
The EV210’s Φ27.5 × 57.6mm cylindrical form factor is specifically optimized for direct SMA-port connection to lightweight drone autopilots, compact GNSS navigation modules, and survey UAV flight controllers — eliminating the need for mounting brackets or cable extensions in most integration scenarios. The compact diameter of 27.5mm fits the GNSS antenna ports and mounting bosses of the most widely deployed lightweight agricultural and inspection drone platforms. The cylindrical vertical profile minimizes lateral aerodynamic forces on the antenna during high-speed flight maneuvers, reducing vibration-induced connector stress on the autopilot SMA port.
Exceptionally Low Noise Figure of 1.3dB
The EV210’s LNA achieves a noise figure of 1.3dB or less — among the lowest available in a drone-class GNSS antenna. A lower noise figure means less thermal noise is added to the received GNSS signal during amplification, directly improving the signal-to-noise ratio delivered to the connected GNSS receiver. This translates to faster satellite acquisition, more reliable signal lock in challenging environments, cleaner carrier phase measurements for RTK positioning, and improved receiver sensitivity for low-elevation satellite tracking. For lightweight UAV applications where the GNSS receiver is often a compact, lower-sensitivity module, the EV210’s ultra-low noise figure provides a meaningful improvement in overall positioning system performance.
BeiDou B3 Global Network Frequency
Full BeiDou B1/B2/B3 support — including the globally networked B3 frequency — provides significantly enhanced positioning stability and satellite availability for agricultural, inspection, and surveillance drone operators across Asia-Pacific, the Middle East, and all BeiDou coverage regions. B3 adds additional satellite signals for ambiguity resolution, improving RTK fix reliability and initialization speed — directly benefiting precision spray pattern accuracy for agricultural drones and corridor-following precision for power line inspection UAVs.
Rubber Pad Base for Vibration Isolation
The EV210 incorporates a rubber pad base that provides mechanical vibration isolation between the antenna and the drone airframe — reducing transmission of high-frequency motor and propeller vibration into the antenna element and connector interface. Vibration isolation protects the SMA connector from mechanical fatigue during extended agricultural and inspection drone operations, and reduces vibration-induced phase center movement that can degrade carrier phase measurement quality in precision RTK positioning applications.
IP67 Waterproof After Mounting
IP67 waterproof and dustproof rating after mounting — with IP65 as a standalone antenna — provides reliable protection against agricultural spray drift, rain during flight, dust from dry field environments, and humidity in coastal, tropical, and industrial monitoring applications. The IP67 rating enables the EV210 to be integrated into drone designs without additional waterproofing provisions for the antenna, simplifying UAV design and reducing assembly complexity and weight.
High Out-of-Band Interference Rejection
Strong out-of-band signal rejection protects GNSS reception from the full range of interference sources encountered in drone operations — including UAV ESCs and motor controllers, FPV and HD video transmission systems, telemetry radios, 4G/LTE command and control links, power line electromagnetic emissions, and cellular base station signals. By maintaining clean GNSS signal reception despite these interference sources, the EV210 delivers stable positioning performance and prevents the unexpected fix loss events that can compromise mission safety for autonomous inspection, surveillance, and agricultural drone operations.
