Description
Product Overview EV108 UAV GNSS Aviation Antenna — Multi-Frequency Four-System GPS / BDS / GLONASS / Galileo
Multi-Frequency Aviation GNSS Antenna | GPS L1/L2/L5 · BDS B1/B2/B3 · GLONASS G1/G2/G3 · Galileo E1/E5b/E6 · L-Band | IP67 | 60g | UAV · Agriculture · Aerial Photography · Telemetry
The EV108 UAV GNSS Aviation Antenna is a compact, lightweight, multi-frequency four-system GNSS antenna engineered for the demanding accuracy, reliability, and environmental performance requirements of commercial and professional UAV operations. Supporting GPS L1/L2/L5, BeiDou B1/B2/B3 — including the globally networked B3 frequency for enhanced positioning stability — GLONASS G1/G2/G3, Galileo E1/E5b/E6, and L-Band, the EV108 provides the broadest multi-system multi-frequency signal coverage available in a UAV-class antenna, maximizing satellite availability, improving positioning geometry, and reducing fix time across all geographic regions and operating environments.
Weighing only 60 grams with a flat-profile Φ90 × 24.6mm form factor, the EV108 is designed for direct integration onto UAV airframes, drone top plates, and vehicle rooftops where minimizing weight and aerodynamic profile are critical operational requirements. Four M4.3 mounting holes at 70mm pitch diameter provide secure, vibration-resistant panel mounting that maintains antenna position and orientation through the high-frequency vibration, rapid acceleration, and dynamic flight loads typical of agricultural spray drones, inspection UAVs, and fast-moving aerial photography platforms.
The EV108 incorporates an O-Ring sealed waterproof construction achieving IP67 waterproof and dustproof rating when assembled — and IP65 as a standalone antenna — providing reliable protection against rain, spray, humidity, and dust in the outdoor environments where agricultural, inspection, and surveillance drones operate daily. Combined with operating temperature range of -40°C to +85°C, the EV108 maintains full antenna performance through extreme weather conditions encountered in field agriculture, arctic survey, tropical disaster response, and industrial inspection missions.
Strong out-of-band interference rejection effectively suppresses signals from 4G/LTE cellular base stations, industrial RF sources, and other radio systems operating adjacent to GNSS frequencies — maintaining stable satellite lock and positioning accuracy in the electromagnetically complex environments near urban infrastructure, power lines, and industrial facilities where inspection and patrol drones frequently operate. The BeiDou B3 frequency support particularly improves system stability across Asia-Pacific and Middle East regions where BeiDou constellation density is highest, providing additional positioning redundancy for critical agricultural and infrastructure inspection missions.

Technical Features — Detailed
Wide Beam Width with Low Elevation Angle Reception
The EV108’s wide beam width and optimized antenna element geometry achieve strong signal reception at low satellite elevation angles — critical for UAV operations in environments where buildings, terrain, and vegetation partially obstruct the sky. Agricultural spray drones operating at low altitude over crop fields, inspection drones flying along power line corridors, and surveillance UAVs in urban environments all benefit from the EV108’s ability to receive satellite signals in seriously blocked environments where competing antennas lose lock. Maximum gain of 2.5dBi with full 360° azimuth coverage ensures consistent signal reception regardless of UAV heading and bank angle during flight maneuvers.
BeiDou B3 Global Network Frequency Support
The inclusion of BeiDou B3 — the globally networked BeiDou frequency — is a key differentiator for agricultural and inspection drone operators across Asia-Pacific, the Middle East, and expanding BeiDou coverage regions. B3 support provides additional signal redundancy, improved positioning geometry, and faster RTK initialization times by increasing the number of usable satellites available for ambiguity resolution. For plant protection drones executing precise spray patterns and power line inspection drones following narrow corridors, the additional positioning stability from B3 directly translates to more accurate flight paths and safer autonomous operations.
Galileo E6 Support for Future PPP-RTK
The EV108 supports Galileo E6 — the signal band used by Galileo’s High Accuracy Service (HAS) for global PPP-RTK corrections broadcast directly from satellites. As Galileo HAS service coverage expands, E6-capable antennas will enable UAV GNSS systems to receive centimeter-level PPP corrections without requiring cellular connectivity or a local base station — particularly valuable for long-range inspection missions, remote agricultural operations, and disaster surveillance in areas without CORS network coverage or 4G connectivity.
O-Ring Sealed IP67 Construction for UAV Environments
The EV108 uses O-Ring sealed construction to achieve IP67 waterproof and dustproof rating when assembled on the UAV airframe, and IP65 as a standalone antenna. This dual-rating approach ensures that the antenna provides reliable protection against agricultural spray drift, rain during flight operations, dust from dry field environments, and humidity in coastal and tropical surveillance missions. The O-Ring seal maintains its effectiveness through the thermal cycling and mechanical vibration of commercial UAV operations, providing long-term reliable weatherproofing without maintenance.
Vibration-Resistant Panel Mount Design
Four M4.3 mounting holes arranged on a 70mm pitch circle diameter provide a secure four-point panel mount that resists the high-frequency vibration from UAV motor and propeller rotation that can loosen single-connector antenna mounts over time. The flat 24.6mm profile minimizes aerodynamic drag on the UAV airframe, and the compact Φ90mm diameter fits the top plate dimensions of the most widely used agricultural and inspection drone platforms. TNC-K connector provides robust, vibration-resistant RF connection compared to SMA connectors in high-vibration UAV applications.
High Out-of-Band Interference Rejection
Strong out-of-band signal rejection protects GNSS reception from interference generated by the UAV’s own electronic systems — including ESCs, FPV video transmitters, telemetry radios, and LTE data links — as well as external interference from cellular infrastructure, industrial transmitters, and power line electromagnetic emissions encountered during inspection missions. By maintaining clean GNSS signal reception in electromagnetically complex UAV operating environments, the EV108 reduces positioning errors, prevents fix loss, and improves overall mission reliability.
