Small loop antenna
I have been experimenting with loops and found them to be very good Rx antennas. They have a useful null and provide a wonderfull drop in noise to bring the DX

The DCTL Antenna Smallloop
The construction material is simply 300 ohm heavy duty TV twinlead
The Ferrite Rod Antenna
The ferrite has the effect of intensifying the magnetic field inside the loop. The is produced by the high permeability, of the ferrite material
Wideband active loop antenna
Wideband small magnetic loops (WSM loop) are used already 3-4 decades and I was curious to see what can be reached with them and to evaluate their usefulness as a wideband SDR input
Magnetic 80m band receiving antenna
Small active fully balanced an screened receiving loop antenna 15 kHz 36 MHz
Automatic Magnetic Loop Antenna Controller
This controller has been designed to automate the control of magnetic loop antennas

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
