Dipolo a "V" invertita trappolato per 40 e 80 metri
La prima parte, dal centrale o balun alla trappola, risonante sui 40 metri, che avrA' una lunghezza di circa 9,90 metri per braccio, e l'ultima parte, dalla trappola all'isolatore, che porta in risonanza tutto il dipolo sugli 80 metri, con una lunghezza di circa 7 metri per braccio queste sono lunghezze che variano da installazione a installazione

G5RV Antenna
The G5RV antenna is probably one of the most maligned antennas in the world
G5RV Formula a simple multiband antenna
Most people think that the famous G5RV antenna was designed as a multi-band antenna, but in fact, it was actually designed as a three - half waves in phase antenna for 14 Mhz
G5RV multi-band antenna
The G5RV, with its special feeder arrangement ladder line, is a multi-band centre-fed antenna capable of very efficient operation on all HF
How High should my Dipole be
I frequently hear the question: how high should my dipole be? Or alternatively, will my dipole work well at this or that height?
