J-pole antenna line coaxial cable
jpole 70 and 23cm where the dimensions of the antenna are reduced. The adaptation of the impedances can be done by deviating more or less the element

J-POLE per i 144 MHz
From the analysis of the structure the j-pole is the direct consequence of Zeppelin with the radiator rotated 90 degrees
Coax J-Pol-Enkel J-Pole-Dobbel J-Pole
The J-Pole antenna has its name from the letter J, as it resembles a J.This is a very good round-beam antenna for VHF and UHF, but in practice it becomes too short for the shortwave area.

Compact Full Sized J-Pole
I propped it up in the living room and put it on the air with 45 watts. My worst SWR is 1.6 and that’s in the very top of 2 meter
