GNSS Antennas by Frequency Band

Choosing the right GNSS antenna by frequency band depends on the required accuracy, receiver compatibility and application. Our GNSS antennas by signal band include L1, L1/L2, L1/L5, L1/L2/L5 and All-Band options. L1 antennas are ideal for cost-effective positioning, while dual- and multi-frequency GNSS antennas provide the signal diversity required for high-precision and centimeter-level RTK applications. All-Band GNSS antennas offer maximum multi-constellation and multi-frequency compatibility with GPS, GLONASS, Galileo and BeiDou.

Choose the Right GNSS Antenna by Signal Band

Selecting the correct frequency band is the first step toward centimeter-level RTK accuracy. L1 antennas are ideal for cost-sensitive applications and basic positioning, while dual-band L1/L2 and L1/L5 antennas significantly reduce multipath errors and improve fix reliability in challenging environments. For maximum performance across all satellite constellations, All-Band antennas support every GNSS frequency simultaneously — GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2/B3, and Galileo E1/E5/E6.

GNSS Frequency Bands Explained

ELTEHS manufactures antennas for L1, L1/L2b, L1/L5a, L1/L2/L5, and All-Band GNSS operation. Each design is optimized for low phase center variation, stable signal tracking, and consistent RTK convergence time. All antennas are compatible with leading GNSS receivers from u-blox, Septentrio, Unicore, and Bynav.

Professional-Grade Performance Across Every Application

Whether you are building a UAV payload, a precision agriculture system, a machine control unit, or a geodetic base station, the right signal band determines your achievable accuracy. Our antennas are field-tested for surveying, autonomous navigation, CORS stations, and timing synchronization — delivering dependable phase center stability across all operating conditions.

FAQ: GNSS Antennas by Frequency Band

What is the difference between L1 and L1/L2 GNSS antennas?

L1 antennas receive a single frequency and are suitable for sub-meter or basic RTK applications. L1/L2 dual-band antennas receive two frequencies simultaneously, which allows the receiver to resolve integer ambiguities faster and achieve centimeter-level accuracy even in partially obstructed environments.

Do I need an All-Band antenna for RTK surveying?

Not necessarily. L1/L2 or L1/L2/L5 antennas are sufficient for most professional RTK workflows. All-Band antennas become advantageous when working with a full-constellation receiver like Septentrio or Unicore, where every additional frequency improves convergence time and robustness in urban canyons or under tree canopy.

Which antenna supports GPS, GLONASS, BeiDou, and Galileo simultaneously?

Any antenna from our L1/L2/L5 or All-Band categories covers all four major GNSS constellations. Single-band L1 antennas also receive signals from all constellations, but only on the L1 frequency layer.

What does L5 frequency add to GNSS positioning?

L5 is a newer, higher-power signal with a wider bandwidth than L1 or L2. It improves multipath rejection, speeds up RTK initialization, and is required for safety-critical applications such as autonomous vehicles and aviation-grade navigation.

Can I use an L1 antenna for drone or robot navigation?

Yes. L1 antennas are lightweight and compact, making them well suited for UAV and robotics platforms where size and weight are critical. For applications requiring centimeter-level RTK accuracy in real time, an L1/L2 or L1/L2/L5 helix antenna is the recommended choice.
