Problem 1: Parts. Red-Flagged Parts. Any plans with the following parts are not plans using “common” parts: 3/8”-24 fine-threaded rod. 3/8”-24 fine-threaded nuts. “CB Antenna” mounts – SO-239 to 3/8”-24 adapter. 300Ω TV twinlead. Didn’t even try to find TV twinlead or a CB mount locally – it’s 2021! I did try to find find-threaded rods locally:
A home made J-Pole antenna for 50 MHz. This article describes how to build a J-Pole antenna for the 6-meter amateur radio band. It's a good choice for those who want an antenna with better performance than a simple wire dipole, but at a lower cost than buying a commercial antenna.
Online calculator for J-Pole antennas. The J-pole antenna consists of a short and a long vertical pole with a feed point near the bottom. The antenna looks like the letter J, hence the name J-pole antenna.
