A coaxial collinear antenna for 70 CM
The guiding principle is that we have multiple 1/4 wave elements fed in series , the radiation from each adds in phase to produce a large vertically polarised omni-directional antenna with bstantial gain td>
Antena Multibanda Colinear para HF
A build of a 2-element 1/2 wave collinear J-Pole a resonant frequency toward the lower end of the 2-meter Amateur band and a VSWR of 1.5:1 or better over the entire band
Antenna collineare omnidirezionale ad 8 dipoli per i 2.4GHz
Iniziamo a levare il conduttore centrale del cavo sat, rimuovendo sia la calza che l'isolante interno del centrale
