L'antenna oltre che di dimensioni ridotte doveva avere un'e fficienza tanto elevata
Dave's Loop Antenna Page
The outside dimensions are 20 inches 51 cm per side. 105 feet 31.5 m of wire will be just enough, including the leads to the capacitor and terminals
Due antenne a quadro per onde medie e lunghe
L'idea, del resto non nuova, mi e' venuta una volta che ho aperto il mio computer per apportarvi una modifica

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
