Description
Product Overview EV220 Multi-Frequency Drone Antenna — Four-System GPS / BDS / GLONASS / Galileo UAV GNSS Antenna
Multi-Frequency Drone GNSS Antenna | GPS L1/L2 · BDS B1/B2/B3 · GLONASS G1/G2/G3 · Galileo E1/E5a/E5b | IP65 | Flat Panel Mount 49.8×38mm | 600mm Cable | Lightweight UAV · Agriculture · Survey · Patrol The EV220 Multi-Frequency Drone Antenna is a flat panel-mount, four-system GNSS antenna engineered for direct airframe integration into lightweight UAV platforms and vehicle-mounted positioning systems requiring the broadest possible multi-constellation signal coverage in a minimal profile form factor.Supporting GPS L1/L2, BeiDou B1/B2/B3, GLONASS G1/G2/G3 and Galileo E1/E5a/E5b, the EV220 covers all four constellations across multiple frequencies. Full BeiDou B3 coverage is included, which many competing drone antennas omit. The EV220’s ultra-low noise figure of 1.3dB or less — combined with 33±2dB LNA gain — delivers exceptional signal quality to connected GNSS receivers across all supported frequency bands. A noise figure of 1.3dB is among the lowest in any commercial drone-class GNSS antenna, providing measurably better carrier phase measurement quality, faster satellite acquisition, more reliable RTK ambiguity resolution, and better positioning performance in low-signal environments including partial sky obstruction, high electromagnetic interference, and weak-signal low-elevation satellite tracking. This makes the EV220 the preferred choice for precision agricultural applications, high-accuracy survey mapping, and inspection drones where positioning accuracy directly determines mission quality. At 49.8 × 38mm flat panel form factor with four Φ3.2 corner mounting holes on a standard 40 × 40mm grid, the EV220 fits the top plate mounting patterns of the most widely deployed lightweight drone platforms — enabling flush airframe integration that eliminates the aerodynamic drag and mechanical vulnerability of protruding antenna designs. The 600mm pre-fitted SMA pigtail provides cable routing flexibility for clean, strain-relief protected connection to autopilot GNSS ports inside the drone body, with sufficient length for most commercial lightweight drone frame depths. BeiDou B3 global network frequency support provides enhanced positioning stability and satellite geometry for operations across Asia-Pacific, the Middle East, and all BeiDou coverage regions — with particular benefit for agricultural spray drones and power line inspection UAVs where consistent RTK fix reliability directly affects mission efficiency and safety. GLONASS G3 support adds the third GLONASS frequency for improved atmospheric correction and better performance at high latitudes. IP65 protection rating ensures reliable field operation in rain, dust, and agricultural spray exposure during daily UAV operations.

Technical Features — Detailed
Flat Panel Form Factor with 600mm Pigtail Cable
The EV220’s flat 49.8 × 38mm panel form factor and four-corner Φ3.2 bolt mounting pattern enable flush integration directly onto drone top plates, vehicle rooftops, and survey equipment enclosures — completely eliminating the protruding profile of cylindrical and dome antennas. The low 1.0mm radiating element profile above the mounting surface creates minimal aerodynamic disruption on high-speed aerial photography and patrol drone platforms. The 600mm pre-fitted SMA pigtail cable provides critical routing flexibility for internal cable management, accommodating a wide range of drone frame depths and autopilot mounting positions without requiring additional cable extension adapters or imposing stress on GNSS receiver SMA ports during vibration and thermal expansion.
Galileo E1/E5a/E5b Triple-Frequency Support
The EV220 supports all three operational Galileo frequency bands — E1, E5a, and E5b — providing complete Galileo constellation utilization.Multi-frequency coverage matters because a second and third civil frequency lets the connected receiver model and remove ionospheric delay, which is the largest remaining error source in high-precision positioning over longer baselines. For UAV and vehicle-mounted systems, tracking E5a alongside E1 and E5b gives the connected receiver the dual-frequency observations it needs for reliable RTK ambiguity resolution over longer baselines.
GLONASS G3 Third Frequency
Full GLONASS G1/G2/G3 support adds the third GLONASS frequency, providing additional signal channels for ionospheric modeling and correction, improved positioning robustness at high latitudes, and enhanced multi-frequency ambiguity resolution for RTK applications. For drone operators in northern Europe, Russia, Canada, and other high-latitude regions where GLONASS satellite geometry is strongest, G3 support provides measurable improvements in positioning availability and RTK fix reliability.
Ultra-Low 1.3dB Noise Figure LNA
The EV220’s LNA achieves a noise figure of 1.3dB or less — delivering exceptionally clean GNSS signal amplification across all supported frequency bands. This ultra-low noise performance improves carrier phase measurement signal-to-noise ratio, accelerates satellite acquisition for faster RTK initialization, enables reliable tracking of weak low-elevation satellites, and maintains positioning performance in environments with elevated RF background noise. For precision agricultural UAV applications where centimeter-level spray accuracy is required, and for inspection drones flying in high-interference electromagnetic environments near power infrastructure, the EV220’s superior noise performance directly translates to better mission outcomes.
High Out-of-Band Interference Rejection
Strong out-of-band signal rejection suppresses interference from 4G/LTE/5G cellular base stations, video transmission systems, telemetry links, WiFi networks, power line electromagnetic emissions, and UAV onboard electronics — maintaining stable GNSS lock and positioning accuracy in the complex electromagnetic environments where traffic patrol, power line inspection, and public security monitoring UAVs operate. High rejection at cellular frequencies is particularly important for drones operating in urban and peri-urban environments where LTE and 5G signals are densely distributed.
Wide Beam Width with Low Elevation Angle Reception
Wide beam width and optimized antenna element design enable reliable satellite signal reception at low elevation angles — essential for UAV operations in partially obstructed environments including agricultural fields surrounded by trees, urban survey sites, disaster areas with debris, and power line corridors flanked by vegetation and structures. Full 360° azimuth coverage ensures consistent signal reception through all drone bank angles and heading changes during autonomous flight maneuvers.
