electroschematicsImage: electroschematicsThis active antenna schematic can be used to frequency range from 10 KHz to 100 MHz. The length of the Antenna can be between 0.5 to 1 meter long. The power consumption is 20-30mA. All capacitors in this circuit are disc ceramic. Fixed-value resistors are 1/.-or 1/2-W carbon. active antenna circuit : Antenna Circuits : RF Circuits Is this answer helpful?Thanks!Give more feedbackThanks!How can it be improved?How can the answer be improved?Tell us how Active Antennas Schematics / Circuits / Notes Active Antennas Schematics / Circuits / Notes.
