5/8 wave J-pole antenna for 145 MHz

Описание к видео 5/8 wave J-pole antenna for 145 MHz

A 5/8 wave J-pole antenna, that I made from copper tubing, a piece of steel wire from a mobile CB antenna, and other stuff. Works very well, has a SWR of 1.2-1. And also what I like about it, is that I can earth it at the bottom, so it's "lightning protected". 73!
