Radio Field Indicator Circuit

A rf field indicator is required to verify power stages and transmitters antennas. With this radio field indicator you can measure radiated energy from antenna. This circuit is very sensitive, a weak signal is enough. A 30cm long wire is enough as a antenna.
The S2 commutator allows to select :

  • 480KHz … 2.4MHz
  • 2.4MHz … 12MHz
  • 12MHz … 40MHz
