Frequently Asked Questions
Q: What frequency does this circularly polarized GPS antenna operate at?
A: This directional antenna is specifically tuned to 1575MHz, which corresponds to the GPS L1 and BD (BeiDou) satellite navigation frequency bands, making it ideal for high-precision GPS receiver and navigation system applications.
Q: What does circular polarization mean and why does it matter for a GPS antenna?
A: Circular polarization means the antenna radiates and receives signals in a rotating electromagnetic field pattern. For GPS and satellite navigation applications, this significantly reduces multipath interference — signal reflections off surfaces — resulting in more stable, accurate signal acquisition compared to linearly polarized antennas.
Q: Can this antenna be used for drone FPV or image transmission systems?
A: Yes. With its 14.5dBi high gain and wide frequency band characteristics, this antenna is well-suited for UAV/drone image transmission setups in addition to GPS and BD navigation use, providing strong directional signal focus for extended range applications.
Q: Is the connector type or cable included with the antenna?
A: The package includes 1 piece of the circularly polarized directional antenna. Please refer to the product images or contact us prior to purchase to confirm connector compatibility with your specific equipment.
