Amplifier AD8129 for Active Magnetic HF Antenna 1MHz-20MHz for Hula Loop

Amplifier AD8129 for Active Magnetic HF Antenna 1MHz-20MHz for Hula Loop

Active HF Antenna AMPLIFIER project
will work for receiving shortwave HF/SSB/AM radios 

you set frequency range with hula-loop diameter and  tuning potentiometer
Loop coil are not included, you need to make your own coil (simple way - RG6 coax)

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. For example with 60cm diameter hula-loop turn you can get approximately 5MHz- 15MHz range. 
 
BNC connector for RF
ONLY Preamplifier AD8129 for Active Magnetic HF Antenna 1MHz-20MHz for Hula Loop 

You will get 

- soldered and testes preamp (30dBm) on AD8129 in waterproof box 

You need

- Magnetic loop (RG6 coax with lenght about 1-6 meters)

- power supply 12 VDC 100 mA or more (connector 5.5*2.1mm)
