Hi all,
In order to improve my range, I bought this week a Low Noise Amplifier SPF5189Z.
It's a 5V amplifier and I connected it to pin n2 and 14 of my GPIO raspberry pi. Pins n 4 and 6 are dedicated to the Fan.
When I try this following configuration, I have no signal:
Antenna - 5m SMA Cable - LNA - SMA to MCX adapter - DVB T dongle - Raspberry Pi.
Without the LNA, everything is fine with 250 messages per second.
Do you have any idea of what may be the issue ?
