This is a simple version of the typical 2 Meter J-Pole. This version has been slimmed down to fit inside of some standard 3/4" PVC piping. The coax must be connected 1.25" inches from the bottom of the antenna and the center conductor and shield must be soldered directly next to each other. The coax should be kept as short as possible going to the SO-239 mounted on the PVC T. I used a PVC pipe cap for the SO-239.
