Introducing the ZD-LB-1500/1700M Directional Antenna, a high-performance, circularly polarized antenna engineered for precise signal transmission and reception in the 1500MHz to 1700MHz frequency band. This antenna is specifically designed for applications requiring high gain, directional coverage, and resistance to multipath interference, such as GNSS augmentation, drone communication links, and specialized wireless data transmission.
Unlike standard linearly polarized antennas that suffer from signal degradation due to polarization mismatch, this antenna utilizes Right-Handed Circular Polarization (RHCP). This design ensures stable signal reception regardless of the orientation of the transmitting antenna, making it ideal for mobile and dynamic environments. With a gain of 10-20dBi, a half-power beamwidth of 20°-40°, and a rugged, waterproof fiberglass radome, this antenna delivers the reliability and performance required for mission-critical operations.
This antenna is specifically tuned for the 1500MHz to 1700MHz frequency range, covering critical bands such as:
GNSS Augmentation: GPS L1, BeiDou B1, and other satellite navigation signals.
Drone Communication: Telemetry, video, and control links.
Specialized Wireless Data: Industrial, scientific, and medical (ISM) applications.
Public Safety: Emergency response and law enforcement communications.
The antenna delivers a gain of 10-20dBi, providing a strong, directional signal that can penetrate challenging environments. The directional diagram (Orientation) and half-power beamwidth of 20°-40° make it ideal for point-to-point and point-to-multipoint links where precise aiming is possible. This high gain ensures maximum signal strength and range.
The antenna utilizes Right-Handed Circular Polarization (RHCP), which offers significant advantages over linear polarization:
Multipath Mitigation: Circular polarization is less susceptible to signal degradation caused by reflections from buildings, terrain, and other obstacles.
Polarization Mismatch Immunity: Unlike linear antennas, circular polarization does not suffer from severe signal loss when the transmitting and receiving antennas are not perfectly aligned.
Improved Link Reliability: The result is a more stable and reliable wireless link, even in challenging RF environments.
The antenna features an Axial Ratio of ≤3dB, ensuring high polarization purity. This is critical for applications requiring precise circular polarization, such as GNSS and specialized communication systems.
The antenna features a Standing Wave of ≤2, ensuring excellent impedance matching and minimal signal reflection. This protects connected transmitters and ensures efficient power transfer.
The antenna is built for outdoor deployment:
Antenna Materials: Base plate aluminum, spiral copper, and outer cover fiberglass (waterproof).
Size: φ130mm x L600mm (reflector plate φ300mm).
Weight: 3kg.
Interface: N-50K connector for reliable, weather-resistant connections.
Despite its high gain and rugged construction, the antenna is relatively compact and lightweight (3kg), making it easy to install on masts, poles, or vehicle roofs.
