FULL KIT Preamplifier for Flag or Magnetic Hula Loop HF Antenna AD8129

Description

Do It Yourself Kit for soldering
Active HF Antenna AMPLIFIER project
will work for
receiving shortwave HF/SSB/AM radios
you set frequency range with hula-loop diameter and  5K tuning potentiometer
Loop coil is not included, you need to make your own coil
Electrical circuit of this active antenna board based on high impedance differential amplifier wired across the loop. Frequency tuned with varicap. By selecting size and inductance of hula-loop turn you can set desired HF range of the antenna. Manual station tuning is done with external 5K potentiometer. For example with 60cm diameter hula-loop turn you can get approximately 7MHz- 20MHz range. The PCB allows to connect additional parallel toroid coil (
coils or toroid are not included
) to shift the frequency range up by H/L switch (or you can switch between additional turns in loop to shift frequency range down).
