VERY IMPORTANT

This preamplifier LNA is highly efficient and need to be use with caution, never use near strong signals (FM radio station amateur radio, walkie-talkie, etc.) under penalty of "grill" your device immediately SDR HackRF One or AirSpy!

How to protect the LNA from ESD?

The static discharge can damage the LNA if it is not protected and used properly.

1 - Never leave the LNA plugged permanently or placed permanently behind an antenna on the mast
2 - Disconnect the antenna and ensure proper grounding of the LNA and antenna, before reconnecting the antenna cable discharging static electricity
3 - It is also possible to add extra protection diode BAV99 welding (scratch first location) to the input of the antenna as shown in green on the following picture:

So if lightning the diode will be damaged but not the rest of the LNA card.

No LNA will be returned or exchanged due to misuse.

The warranty does not cover damage that may result from an assembly error, an incorrect antenna setting (ROS), a maximum input power not respected, a short circuit of the power supply or coaxial line and damage from electrostatic discharge.
