Full-range Helical Antenna



Product Basic Information

Product Model: DY-GGBR033P00B

Applicable Frequency Bands: BDS: B1/B2/B3; GPS: L1/L2/L5; GLONASS: L1/L2; Galileo: E1/E5a/E5Be6


Product Usage

This antenna utilizes an eight-arm coupling and four-feed point feeding technology to support the reception of multi-frequency satellite navigation signals for Beidou-2, GPS, GLONASS, and GALILEO systems, covering L1, L2, and L5 bands. It is equipped with a low-noise amplifier and features a two-stage filter, which provides excellent out-of-band suppression and strong anti-interference capabilities, ensuring normal operation in harsh electromagnetic environments. It meets the current demands for multi-system compatibility and high-precision measurement. Suitable for applications that require a compact size and light weight, such as drones, mini-RTK, and portable devices like sub-meter handhelds/tablet computers.


Key Characteristics

Features high out-of-band rejection and high linearity, ensuring normal operation even in the presence of strong interfering signals;

Utilizes multi-arm helical technology, ensuring right-hand circular polarization and phase center performance, reducing the impact of measurement errors;

The antenna element has high gain and low gain roll-off, providing good reception of low elevation angle satellite signals;

Exquisite low noise, high gain amplification, and excellent out-of-band suppression;

Electrostatic protection: 15kV (air discharge);

Compact size and light weight, facilitating easy transportation and installation.
