Product Description:
1. The antenna unit adopts a symmetrical layout design to ensure unit performance consistency.
2. The amplification circuit has high gain and low noise figure, and can still ensure a good signal-to-noise ratio of the received signal when connected to a long cable.
3. High gain, wide beam, and good signal reception at low elevation angles, ensuring that satellites can still be collected normally in some severely obscured situations.
4. The power amplifier has high efficiency and stable output power.
