Calcolatore per antenna j-pole

Antenna j-pole Biband vhf-uhf photo demonstrations

The tuning is simple, unscrew nuts and move the clamps up or down until you get the SWR correct

Another approach to the problem is the J-Pole antenna, in this design, the antenna is elevated at least 1/4 wavelength above ground, thus eliminating the ground losses and normalizing the radiation pattern, the Impedance matching between the low impedance feed line and the high impedance of the end of the dipole
