[Elecraft] Portable antenna

[Dan Presley]

No worries-it’ll make a nice winter project. Right now I’m taking full advantage of sunshine before the rainy season starts.

>> Thanks Dave for the reply. That sounds like a great antenna and I’d definitely like to see a picture and maybe a bit more description if you’d care to. I enjoy playing with portable antennas and might try to build something like that over the winter. One that I put together last year was a two element vertical Yagi based on the article by a Japanese ham (forgot the call) in QRP quarterly a few years back. It uses a driven element and a quarter wave reflector,and the reflector uses a quarter wave matching section connected as a radial. Think of basically a ‘U’ shaped setup. The original was suspended from tree branches but I set it up for ground mount using two 20 foot small fiberglass fishing poles. It actually gave some reasonable gain on 20 and you could steer it a bit by moving the reflector.

We’ve either won or placed 2nd in our division for a few years. Nothing beats big wire,but when I’m hiking I gotta rethink everything and go small-thus the AX1/2 and simple wires.
