Had a few free hours on Sunday and put this beast together. It’s a j-pole with a decoupling section at the bottom to reduce common mode currents reflecting down the grounded mast. I was thrilled when my analyzer showed 1:1 SWR at a little over 147MHz and 53 ohms. Successfully hit a handful of repeaters and made a 20 mile simplex contact. It’s base is 10 feet above my single story roof. I’m thinking about going up another 10ft. If things work out, I think I’ll make another one for 6m FM.
