<div dir="ltr"><div>I made a 6m wire ground plane years ago - very simple and easy to tune. worked great. In fact, I made my very first 6m DX (for me) contact with the top of the antenna about 10 - 12 ft up in a tree and the two ground planes staked to the lawn with 2 or 3 ft of cord. <br></div><div><br></div><div>Materials were easy - wire and a SO-239 chassis connector. The vertical element (1/4 wavelength on the freq you want to use) is soldered into the center connector so that you can attach the coax to the antenna and the ground planes are attached to opposite mounting holes on the chassis connector. It doesn't get much simpler than this - everything is 1/4 wavelength. Remember to allow a little extra length for the elements so that you can make a loop for hanging it up and staking it out while still keeping the correct length for the freq used. Upside down Y configuration. The first contact was Arizona! This was done w/o an analyzer based on the math. I think I had Joe K7SQ come over and put his analyzer on it to see what it was doing - checked out fine - just use a tuner.<br></div><div><br></div><div>I used a 6m vertical that I also have for 6m FM
