Multi satellite Multi frequency helical antenna
- Produktbeschreibung
AHG-23 is a multi-satellite single-frequency active spiral antenna designed with multi-arm spiral technology. It supports the L1/L5 band satellite navigation signal reception of GPS, GLONASS systems, and meets the current multi-system compatibility and high-precision measurement It can be widely used in high-precision navigation and positioning occasions such as portable equipment, unmanned aerial vehicles, and navigation dispatching. Accept user customization.
- Technical Features
- Using multi-arm spiral technology to ensure right-hand circular polarization and phase center performance, reducing the impact of measurement errors;
- The antenna unit has the characteristics of high gain and small gain roll-off, which has a good reception effect for low-elevation satellite signals, ensuring that the satellite can still be received normally in some severely obstructed occasions;
- The three-proof outer cover provides a guarantee for the antenna to work in the field for a long time.
