1. The four-arm spiral structure has a relatively stable phase center, which reduces the impact of the antenna on measurement errors.
2. The gain is high, the pattern beam is wide, and the reception effect of low elevation angle signals is good, ensuring normal star collection in some situations with severe obstruction.
3. Equipped with high out-of-band suppression and low-noise amplification circuit, which can effectively resist external electromagnetic interference and has low power consumption to ensure the battery life of the device.
4. Small in size and light in weight, it is suitable for use on various devices that require antenna weight, such as drones and various handheld terminals.
