J-pole antennas have made a name for itself because of their high gain at a comparatively small small size. This type of antenna was invented early in the last century and was employed during WW2 for use in a Zeppelin and was therefore called 'Zepp' antenna. The electrical principle of the wire antenna for shortwave is the same as this J-antenna or J-Pole: a halfwave length or radiator fed by a quarter wavelength feed.

The antenna has a grounded radiator and is thus immune to static charges. The feed requires just one coax cable even for the dual band antenna. The radiating elements for the dual band J-Pole are made of 10 mm aluminum tubes, the tubes for the 4 and 6m version are constructed from 25 to 35mm thick tubes. This results in a very solid design which gives you a longterm stability.
