Cross Dipole Antennas for RTK on Drones: Maximizing Signal Quality and Stability
Why Choose Cross Dipole Antennas for RTK on Drones?
Cross Dipole antennas are an excellent choice for RTK applications, especially on drones, due to their superior ability to filter out reflected signals and interference. These antennas are specifically designed to provide more consistent and uniform reception, both from low and high satellites. If you're working in environments with high multipath interference, such as near buildings or on mountain slopes, a Cross Dipole antenna is your ideal solution for ensuring a reliable RTK connection.
How Cross Dipole Antennas Outperform Other Antenna Types
When compared to traditional antenna types like patch and helix antennas, Cross Dipole antennas stand out because they offer better resistance to interference, which is critical for applications requiring high-precision GNSS signals. Although their phase center is typically larger than that of a patch antenna, making them bulkier, their performance in challenging environments makes them worth the investment. The main disadvantage of Cross Dipole antennas is their higher cost when compared to patch and helix antennas with similar specifications. However, the extra cost is justified for users who need uncompromised performance.
