Choke Balun experiment
I was aware from some early experiments on cores FT240-30 windings would have high resistances as well as fairly high inductive reactance

Balancing is often used to optimally match balanced antennas to unbalanced coaxial cables. These can be made of coaxial cables or toroidal transformers
Balun HF 1,5KW
Vengono illustrati negli schizzi sottostanti, i dettagli costruttivi per la realizzazione di un balun H.F. trifilare in aria in grado di sopportare oltre 1,5KW
Balun 4:1 ferrite, swl-i2-5759
Si tratta di un avvolgimento su barrette di ferrite collegato in parallelo ad un condensatore variabile

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
