Commutatore d'antenna per HF a controllo remoto
Le misure effettuate sul commutatore autocostruito hanno evidenziato una perdita di inserzione dell’ ordine di qualche decimo di dB, un VSWR intorno a 1.2-1.3

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
