The EV106 GNSS Choke Ring Antenna is a professional-grade, multi-system, full-frequency geodetic reference station antenna featuring a miniaturized 3D choke structure design — covering BeiDou B1/B2/B3, GPS L1/L2/L5, GLONASS L1/L2/L3, Galileo E1/E5a/E5b/E6, and L-Band in a single high-performance antenna element. Designed for CORS networks, geodetic survey reference stations, earthquake monitoring systems, bridge and infrastructure deformation monitoring, dock automation, and global navigation satellite system reference infrastructure, the EV106 delivers the phase center stability, multipath suppression, and signal integrity performance required by the most demanding geodetic and precision positioning applications.
The EV106’s defining advantage over conventional choke ring antennas is its miniaturized 3D choke design — achieving the full multipath suppression performance of a traditional large choke ring antenna in a more compact, lighter structure. With phase center error of ±1mm, maximum gain of 6dBi, and a high-gain LNA delivering 50±2dB on both L1 and L2 bands, the EV106 supports cable runs of up to 100 meters between antenna and receiver — enabling flexible reference station installation on towers, rooftops, and remote monuments without signal degradation. IP67 waterproof and dustproof construction ensures continuous unattended outdoor operation for years.

The EV220 is a professional-grade, multi-frequency, four-system drone GNSS antenna supporting GPS L1/L2, BeiDou B1/B2/B3, GLONASS G1/G2/G3, and Galileo E1/E5b/E6 — with a flat panel-mount form factor measuring just 49.8 × 38mm and a pre-fitted 600mm SMA pigtail cable. Designed specifically for lightweight UAVs, agriculture drones, aerial photography platforms, telemetry systems, traffic patrol, disaster monitoring, public security monitoring, power line patrol, and surveying applications, the EV220 delivers broad four-system multi-frequency GNSS signal coverage with an ultra-low noise figure of 1.3dB — in a flat, discreet, airframe-integrated antenna package that minimizes aerodynamic profile and weight impact.
The EV220’s flat panel geometry — secured by four M3.2 corner mounting holes on a 40 × 40mm bolt pattern — integrates flush with drone top plates, survey vehicle rooftops, and compact UAV airframes where a protruding cylindrical antenna would create unacceptable aerodynamic drag or mechanical interference. The 600mm pre-fitted SMA pigtail cable provides routing flexibility for clean, vibration-managed cable management inside drone enclosures and vehicle-mounted installations, eliminating the connector stress that direct-mount antennas impose on autopilot SMA ports during vibration and thermal cycling.
