Multi-frequency Handheld Antenna
The EV006 is a compact, multi-frequency, multi-system handheld GNSS antenna supporting GPS L1/L2, BeiDou B1/B2/B3, and Galileo E1/E5b — designed for surveying and mapping handhelds, tablet computers (PADs), high-precision UAV positioning, disaster monitoring, traffic patrol, remote telemetry, and public security monitoring applications. With a slim bending structure measuring just Φ27.5 × 107.5mm, SMA male screw mount, and IP67 waterproof rating after installation, the EV006 combines professional multi-frequency performance with the portability and ruggedness demanded by field survey professionals and mobile precision applications.
The EV006 delivers 2.5dBi maximum gain with a wide beam width and strong low elevation angle signal reception — enabling reliable satellite tracking even in partially obstructed environments including urban survey sites, forest canopy, and disaster monitoring locations where full sky visibility is limited. The integrated 33±2dB LNA with noise figure of 1.5dB or less ensures clean signal amplification across all supported frequency bands, while high out-of-band suppression protects against interference from cellular base stations and other RF sources common in field survey environments.

Product Overview EV006 Multi-Frequency Handheld GNSS Antenna — GPS / BDS / Galileo Multi-System
Multi-Frequency GNSS Antenna | GPS L1/L2 · BeiDou B1/B2/B3 · Galileo E1/E5b | High Gain Low Elevation | IP67 | SMA Mount | Surveying Handhelds · PADs · UAVs
The EV006 Multi-Frequency Handheld GNSS Antenna is a professional-grade, quad-system multi-frequency passive antenna engineered for the demanding accuracy and reliability requirements of handheld surveying equipment, precision UAV platforms, and mobile field data collection systems. Supporting GPS L1/L2, BeiDou B1/B2/B3 — including the globally networked B3 frequency — and Galileo E1/E5b, the EV006 provides broad multi-system, multi-frequency signal coverage that maximizes satellite availability and positioning accuracy in all geographic regions and operational environments.
A key differentiating feature of the EV006 is its wide working band with particular strength at the BeiDou B3 frequency point — a globally networked signal that significantly improves positioning system stability and redundancy in the BeiDou constellation. Combined with wide beam width and optimized low elevation angle gain, the EV006 receives satellite signals in seriously obstructed environments such as urban street canyons, forested survey areas, and disaster-affected locations where clear sky access is compromised. This makes the EV006 uniquely valuable for the field professionals and first responders who rely on handheld GNSS in the most challenging positioning environments.
The EV006’s compact bending structure — measuring just Φ27.5 × 107.5mm — is specifically designed for integration into surveying handheld terminals, ruggedized tablet computers, and compact UAV frames where space and weight are constrained. The SMA male screw mount ensures secure, vibration-resistant antenna connection compatible with the SMA-J female port standard used across professional handheld survey instruments and UAV navigation modules. IP67 waterproof and dustproof rating after installation ensures reliable continuous operation in rain, dust, mud, and harsh outdoor field conditions.
Strong out-of-band suppression protects the EV006’s signal reception from interference generated by 4G/LTE cellular base stations, WiFi networks, and industrial RF sources — a critical feature for survey professionals working in urban and peri-urban environments where competing RF signals are dense and unpredictable. With operating voltage of DC 3.3V to 12V and current consumption of 50mA or less, the EV006 is fully compatible with the bias-tee power circuits of all professional handheld GNSS survey instruments and UAV navigation receivers.

Technical Features — Detailed
Wide Band Multi-Frequency Reception with BeiDou B3 Support
The EV006’s wide operating band supports GPS L1/L2, BeiDou B1/B2/B3, and Galileo E1/E5b simultaneously. The inclusion of BeiDou B3 — a globally networked frequency that significantly strengthens the BDS constellation’s positioning geometry and signal redundancy — is a key advantage for survey professionals and field operators working across Asia-Pacific, Middle East, and global regions where BeiDou satellite availability is highest. B3 support improves fix reliability, reduces initialization time, and enhances positioning stability in challenging signal environments.
High Gain at Low Elevation Angles
The EV006’s wide beam width and optimized antenna element design achieve strong signal reception at low satellite elevation angles — where many compact handheld antennas struggle. Low-elevation satellite tracking is essential for field survey work in urban areas, forests, mountain valleys, and disaster sites where buildings, vegetation, and terrain obscure the upper sky. By tracking low-elevation satellites that competitors reject, the EV006 improves positioning geometry, reduces DOP values, and maintains reliable GNSS fix in the obstructed environments that field professionals encounter daily.
Strong Out-of-Band Interference Suppression
The EV006 incorporates high out-of-band signal suppression that effectively attenuates interference from cellular base stations (4G/LTE/5G), WiFi networks, broadcast transmitters, and industrial RF sources operating adjacent to GNSS frequencies. This interference rejection maintains GNSS receiver performance and positioning stability in urban survey environments, public security operations, and traffic monitoring deployments where competing RF signals are unavoidable. The result is more consistent positioning accuracy and reduced fix loss in real-world field conditions.
Compact Bending Structure for Handheld Integration
The EV006’s unique bending antenna structure achieves a total length of just 107.5mm with a maximum diameter of 27.5mm — making it one of the most compact multi-frequency GNSS antennas available for handheld integration. The SMA male connector screws directly onto the SMA-J female port of surveying handhelds, ruggedized tablets, and UAV navigation modules — providing a secure, repeatable mechanical connection that maintains signal integrity through the vibration and handling forces of field survey use.
IP67 Field-Ready Protection
With IP67 waterproof and dustproof rating after installation on the complete device, the EV006 provides reliable protection against rain, splash, mud, and dust exposure typical of survey and disaster monitoring field operations. Operating from -25°C to +70°C, the EV006 covers the full range of field survey environments from winter mountain surveys to tropical disaster response deployments.
