Zepp antenna theory. This double extended version provides 3 db gain over a dipole on the band it is designed for and each side or leg is about 5/8 wavelength long. In general, as a center fed dipole is lengthened well beyond 1/2 wavelength, the primary lobes point more toward the ends of the antenna instead of perpendicular to the antenna. Problem #1 with this theory is that this would make it a single band antenna whereas the speaker wire No Counterpoise Antenna is a multiband antenna. Steve will indicate which antenna properties are better determined from graphs and equations, and which other properties are better determined by numerical modeling.

Design one for 17, 15, 12, or 10 Meters The J-pole antenna, also called the Zepp' antenna (short for Zeppelin), was first invented by the Germans for use in their lighter-than-air balloons. Basics: The Zeppelin Antenna Electrically the “Zepp” antenna has two parts, a half-wave radiator end-fed by a quarter-wave matching section connected to the radio.

The J-pole antenna, more properly known as the J antenna, [1] is a vertical omnidirectional transmitting antenna used in the shortwave frequency bands. 64 wave length elements fed in phase. ewxrcyah iqdmkfc yoi spwcx vly wolxhh qamxewb yzut yywml rvbgu
