Antena OSJ dual band VHF / UHF com um cabo
It consists of a half-wave dipole element, which instead of being fed from the center as is more common is fed from one end in this case, the bottom
Antena J-Pole para 146 MHz, 220 MHz, 440 MHz
The antenna, is designed entirely in bronze pipes and the longest rod point A + C, has a total length of 2 Mts 44 cms
Antenne en J alimentee par un cable coaxial
Like the model supplied by a two-wire line, it consists of a radiating element of half-wave length attacked at its lower end by a quarter-wave line
J-antenna supplied by a two-wire line
The J antenna, so called because of its shape, is generally used on 2m and 70cm, even 23 cm and 6m
Antenne verticale VHF Slim-Jim
The Slim-Jim vertical antenna is of the 1/2 wave type supplied at the end end fed and therefore does not require a ground plane unlike a 1/4 wave type antenna
