Multi-star Multi-frequency spiral antenna
GL301JC
Product description
* GL301JC is a multi-star and multi-frequency active spiral antenna, designed with multi-arm spiral technology, supporting compass B2 and B3,
* L1/L2 or L1/L5 tri-band satellite navigation signal reception for GPS, GLONASS and GALILEO systems,
It can meet the needs of multi-system compatibility and high-precision measurement, and can be widely used in portable equipment, UAV and other high-precision guidance
Position the occasion, accept user customization.
Technical characteristics
* Multi-arm helix technology is used to ensure right-handed circular polarization and phase center performance, reducing the impact of measurement errors;
* Antenna unit using air medium, has the characteristics of high gain, small gain roll down, low elevation satellite signal reception Good, to ensure that in some of the more serious occasions can still be normal star;
* 3 protective covers, for the antenna long-term work in the field to provide protection.
