Product Description
The MT-230D GNSS antenna employs four-arm spiral and four-feed point feeding technology, supporting the reception of multi-satellite single-band navigation signals from Beidou II, GPS, GLONASS, and GALILEO systems. It incorporates a built-in low-noise amplifier and two-stage filter, featuring excellent out-of-band suppression and strong anti-interference performance to ensure stable operation in harsh electromagnetic environments. This antenna fulfills the current demands for multi-system compatibility and high-precision measurement applications.
Applications
It is well-suited for scenarios with requirements on volume and weight, such as drones, miniature devices, and sub-meter handhelds/tablets, as well as other portable equipment.
This version refines the phrasing for smoother logic: “with requirements on volume and weight” clarifies the core constraints more naturally than the original; “miniature devices” adds specificity to the vague “miniature” in the original text; and “as well as other portable equipment” ensures the scope of portable devices is fully covered without altering the original meaning.
Technical Characteristics
The antenna leverages multi-arm spiral technology, which not only ensures right-hand circular polarization and stable phase center performance but also minimizes the impact of measurement errors.
The antenna unit features high gain and a small gain roll-off, delivering excellent reception for low-elevation satellite signals.
It is equipped with sophisticated low-noise, high-gain amplification, along with outstanding out-of-band suppression capabilities.
For electrostatic protection, it supports 15KV (air discharge) to safeguard against static damage.
With its compact size and lightweight design, the antenna is easy to carry and install.
