Base Station Antenna

Shengda's high-gain base station antenna can achieve a gain of more than 33dBi by optimizing the radiation unit structure and reflector design. When covering an area with a radius of 10 kilometers, approximately 1,682 ordinary 5G base stations need to be deployed, while Shengda's high-gain antenna only requires 500, increasing coverage efficiency by more than 70%.

Marine Antenna

The fiberglass housing is highly resistant to water and salt spray corrosion, making it suitable for high-humidity marine environments.
The wind-resistant design maintains structural stability in harsh sea conditions and reduces signal jitter.

Car Mobile Antenna

Multi-antenna collaboration: Antenna isolation ≥25dB reduces intermodulation interference between GSM, Bluetooth, and other devices, ensuring synchronous and stable multi-band communications in the vehicle.

Learn More Product

4/5G Antenna

The fiberglass housing provides IP68-rated water and dust resistance, withstanding heavy rain and salt spray, with signal attenuation less than 5% in rainy conditions. The operating temperature range is -30°C to +70°C, covering environments from extremely cold to high temperatures.

Yagi Antenna

Shengda Yagi antennas feature a vertical/horizontal dual-polarization design to mitigate polarization mismatches caused by ship rolling or mountainous terrain, reducing signal attenuation. Certain models utilize right-hand circular polarization to suppress multipath interference from sea surface reflections.
