7 mhz vertical monopol
7 mhz vertical monopole high efficiency half wave vertical radiator fisical lenght 8 mts ,very low radiation angle, multi-loading to keep losses low,good decoupling system , no radials needed , just a short counterpoise

Vertical half-wave aerials for 4m
For vertical use, it is much more mechanically convenient to end-feed an antenna: this will allow it to be mounted higher, and avoids distortion of its omnidirectional polar
Vertical Pancake Dipole 10-20 Meters
The antenna easily loaded 10-20 meters in the vertical configuration but it didnt do well for me on 10 and 17 meters as a horizontal dipole
Verticale con riflettore
Queta antenna l'elemento riflettore ed i radiali son isolati da massa
