End fed antenna
- Un trasformatore 1:64 su cui è collegato un filo lungo lambda/2 della frequenza prescelta, una versione a 3 o 5 bande in modo da avere maggiori chance su più 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

160 meter end fed
With this length of wire a coil of 11 turns is required, resonating the antenna on 1.950MHz with an SWR of 1.5:1
10 20 40m Endfed antenna
It's has a large bandwidth with a low SWR and has no radials
40m End Fed Half Wave EFHW Antenna
The feed point of the EFHW is in the order of 3000 to 5000 ohms while the 1/2 wave dipole will be closer to 50 ohms in the inverted V configuration
