  • Anyone got a Rizla? Portable 'Roll up' Dual band antenna for your go bag.

    Hi Guys, work is thin so I'm sat at home on YT and came across an interesting video with links to an article about a very portable dual band (VHF-UHF) antenna with excellent propagation. The article is here (attached)

    Basically a J-Pole antenna design by Ed Fong (K6LCS) made from twin lead cable and coax. You can roll this up and have it in your go bag with your favourite chinese (or other) HT radio. Simply hoy a bit of cordage over a tree branch and raise the antenna up off the deck.

    I'll be ordering some components to make both the portable (DBJ-2) and enclosed (DBJ-1) versions.

      When new to radio people see antennas like this, often their first thoughts are it can't be any good.
      These roll up antennas are fantastic.
      Have fun making them

        We used to use all sorts back in the day when I was a Scaleyback Tech in the Sigs.

          I've made a few dodgy looking ones in my time, but they've worked because the physics was right 😀
