Antena Dipolo para 40 y 80 metros Esta antena dipolo para las bandas de 40 y 80 metros tiene un buen rendimiento y es sencilla de construir, por ello no debería dar problemas en su construcción. Los dípolos de media onda (y sus múltiplos impares) tienen en el punto de alimentación una impedancia, teórica de 75 ohmios que al ser parecida a la del transmisor (50 ohmios) nos permitirá su alimentación sin problemas sin tener que recurrir a adaptadores de impedancia, en el peor de los casos la R.O.E. debería estar a 1,5. Si las ramas del dipolo se colocan en "V" invertida formando un angulo de 120 a 90 grados, su impedancia desciende acercándose hasta los 50 ohmios lo que parece ser ideal. No obstante se deforma ligeramente el lóbulo de radiación y al acercarse sus extremos al suelo u obstáculos adyacentes se empeora su rendimiento.

________________________________________________________ Costruire un'antenna J-Pole Dual Band 2M / 70 cm Questa antenna ( erroneamente chiamata j-pole dagli autori ma più simile ad un sleeve dipole) funziona ed è facile da costruire. facile da usare al coperto o in portatile su 70 cm o dual band 2M e 70 cm. Avrete bisogno di un SO-239, connettore per montaggio su telaio, asta per saldatura rivestita in rame 1/16 e chiusure n. 6. Il passo chiave nel fare questa antenna è spaziatura degli elementi 0.60 pollici come la distanza SO-239 è più vicino a 1/2 pollice. Costruire un collegamento eccentrico o decentrato usando una vite 6-32 e saldare il lato della vite sul lato dell'asta di saldatura per formare l'elemento 1/4 di lunghezza d'onda. Vedi i dettagli nella foto qui sotto. Questa disposizione prevede aggiustamenti; la spaziatura può essere variata dalla rotazione per ottenere 0,6 pollici e la sintonizzazione fine dei 6.38 pollici con la posizione verticale della vite.

Peter VK3YE recently published a 2m rectangular loop antenna article in Amateur Radio Magazine edition 5 (Sep-Oct 19). The feedpoint impedance of the 2m rectangular loop is 50 ohms thus avoiding the need for a 1/4 wave impedance transformer. Are interested in a 6m oblong loop? I have constructed the lightweight 150 gram (5.2 ounces)…
