ARK-LNA

A low noise amplifier based on the MAR-6 or MAR-8. It was designed with NOAA weather satellites in mind, but might be useful for other VHF transmissions as well.

  • Supply voltage: 6-10V
  • Minimal center frequency: 87.16 MHz
  • Maximal center frequency: 160 MHz
  • Bandwidth: To be determined
  • Gain: 20 dB
