End fed antenna

Un trasformatore 1:64 su cui e' collegato un filo lungo lambda/2 della frequenza prescelta. una versione a 3 o 5 bande in modo da avere maggiori chance su piu' frequenze. Un filo di rame teso ha un'impedenza superiore ai 3.3 K ohm e quindi per poter adattare l'impedenza ai 50 ohm della radio, con un toroide FT240-43 - 1:64
