Antenna EFHW vs Dipolo en V invertida
Показать описание
Comparativa entre una antena End Feed Half Wave (EFHW) y un dipolo en V invertida.
Ambos miden 20m de largo, es decir, media onda en la banda de 40m.
Potencia utilizada 500W PEP.
Altura de vértice del dipolo 13m y los extremos sobre 6m +-.
La EFHW va en slopper desde los 4m a los 16m en el extremo no alimentado.
La recepción se realiza online en tiempo real, mediante un receptor SDR situado en Australia.

Comparison between an End Feed Half Wave (EFHW) antenna and an inverted V dipole.
Both measure 20m long, that is, half a wave in the 40m band.
Power used 500W PEP.
Vertex height of the dipole 13m and the ends about 6m +-.
The EFHW sloppers from 4m to 16m at the unfed end.
Reception is done online in real time, using an SDR receiver located in Australia.
