Antenna verticale 6-10-12-15-20m
Un tubo di alluminio di lunghezza elettrica pari a un 1/4 lambda per la gamma dei 20 metri che tramite delle crociere isolanti assolve anche alla funzione di supporto per i conduttori elettrici che risuonano ognuno per una gamma di frequenze

MicroVert Antenna
The MicroVert antenna, designed by , DL7PE, is a short, base loaded antenna that uses the coax shield as a counterpoise
Multiband Semi-Helical Inverted L Vertical
This is my attempt to build an antenna for 80 and 40 meters that will accommodate my installation limitations
Opposite Voltages Fed Two Element Array
Both elements are voltage driven, in opposite phase ,from the feedpoint of element 1 driven there is a 1/2 wavelength cable electrical wavelength to the feedpoint of element 2 reflector
Stealth Multiband Vertical 40-80mt
The Spiderbeam pole is quite a bit more substantial than the fishing rod types that I'd used in the past, but it's still light enough to take up and down in a minute
Vertical fishingrod antenna
This vertical antenna is based on the Ground Plane theory too, with use of the base-loaded radiator
