La J - antenna per 144 MHz
L'antenna ha un basso angolo d´irradiazion e il guadagno e' piu' di 3 dB rispetto ad una ground plane

Before we start, be prepared to experiment! The calculator will get you close or spot on if you’re lucky, but there are so many variables
Slim-Jim 2m VHF Band Antenna
Slim-Jim is easy to built, no radial 145Mhz antenna. It has almost equal gain of a 5/8 lambda
Super J-Pole Collinear
VHF and UHF but for 220MHz a shortage of antenna
