The decision to proceed with the 5 8 wave ground plane antenna was largely based information and analysis provided by the rsgb s. L antenna 5 8 d onda in vhf le antenne piu usate sono le 1 4 l onda e le 5 8 d onda. La figura seguente riporta la distribuzione delle correnti per entrambe le configurazioni. It is found that for a monopole antenna like a quarter wavelength vertical the ground acts as a plane to reflect the radio waves so that an image of the top half of the antenna is seen in the earth.

4 4 out of 5 stars 13. Vhf uhf ground plane. There are usually four radials three being a minimum but you could use up to six. Le seconde hannun guadagno di circa 3db sulle prime.

Home antenne pmr446 ground plane antenna ground plane 1 4 d onda autocostruita per vhf uhf. As the name indicates the antenna ground plane acts as a simulated ground.

Ground plane per i 2 metri questa antenna può essere utilizzata su qualsiasi banda rispettando le dovute dimensioni e non crea problemi. Rugged radios vhf 1 2w spr vhf 1 2 wave no ground plane antenna 144 174mhz. This calculator can be used to design a quarter wave ground plane antenna with radials. Home antenne ehf shf wifi antenne vhf uhf.

Ricordate che il radiatore verticale è 1 4 di lunghezza d onda della vostra frequenza operativa. Sulla lunghezza d onda dei 27 mhz gli elementi radiali dell antenna ground plane vengono realizzati in dimensioni inferiori al quarto d onda. Un altro pregio della 5 8 d onda è quello di ottenere un angolo inferiore di radiazioni. Quando si parla di antenne spesso la gente pensa che ci siano un sacco di cose magiche al riguardo e per questo motivo non ha mai tentato di sperimentare e costruire qualche antenna con le proprie mani.
