VHF Collinear J-Pole : The DIY Super J-Pole Antenna

VHF Collinear J-Pole : The DIY Super J-Pole Antenna: Take your VHF/UHF station to the next level with DIY Super J-Pole guide. Learn how to build this collinear antenna for maximum gain and clear long communication.

If you’ve spent any time in the ham radio world, you know the standard J-Pole is a reliable “workhorse.” But what if you need more “reach” without switching to a complex directional Yagi? Enter the VHF Super J-Pole.

When it comes to omnidirectional antennas, the standard J-Pole is a legendary starter project. But for those who want to push their signal further toward the horizon, the Collinear J-Pole (often called the Super J-Pole) is the ultimate upgrade.

By stacking radiating elements and using a clever “phasing” technique, this design provides a significant gain increase over a standard dipole or J-pole, making it a favorite for builders who value efficiency and distance..
