LNA preamp VHF-UHF SDR
The LNA4ALL is a pre-amplifier and a low-pass filter (LNA) with SMA female RF connectors and for RF frequencies covering all bands from 28MHZ to 2500 MHz.
Power is to build yourself via a 6V/9V by connecting simply 2 power cables or 5V with a modification on the board.
The LNA4ALL can also be powered directly by the SMA female connector (input) connected to HackRF One or Airspy (with changing the card).
