Usage & Safety Notes

A stable 28V / 5A DC power supply is required.
Adequate heat dissipation (e.g., heatsink or cooling fan) is recommended for prolonged high-power operation.
Connection Sequence: First connect the antenna to the RF port, then plug in the power adapter, and finally power on the source device.
The maximum saturated output power can reach 47dBm with an input drive of +10 to +11dBm (at 37dB gain setting).
