Active Antenna Circuit for 10KHz to 100MHz

Hosted circuit

 



This 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.
Active Antenna Circuit for 10KHz to 100MHz

Use the shortest posible length of cable between the antenna and the transistor. Cable 50 or 75 Ohms is suggested, for both input and output.

Looks good, I will give this a try. How would you extend the frequency up to cover the top end of the normal FM band (108MHz?)
