To function as intended, the J-Pole antenna needs electrical isolation from its mount. Here’s why and in technicolor no less.

Hiking, ham radio and hills combined to make the Golden Packet Test a memorable event.

5/8 Wave J-Poles aren’t better than 1/2 Wave J-Poles

Another 5/8 J-Pole Design arranged as a Collinear… can it justify the complexity?

Resolving the mystique surrounding the 5/4 wave antenna comparing center and end fed approaches. One conclusion is the end fed 5/4 wave antenna shows little promise as a vertical antenna for terrestrial use.

Analysis to suggest you really can use a 2 meter J-Pole in the 70cm band.

Longer is not always better in the world of antennas. Such is the case of the 5/4 wave vertical antenna… a Super J-Pole Wannabe Antenna

This J-Pole, Monopole, Coaxial Dipole VHF EZNEC shootout addresses a comment made that no models exist for j-pole and coaxial dipole antenna simulation.

Myths abound concerning how J-Poles do so well. Here is an EZNEC shootout between a 2 meter J-Pole and a Monopole with radials.
