Making a 20m SlimJIM Antenna

Making a 20m SlimJIM/Zepp for use during my Parachute Mobile jumps. Not difficult but it takes a little bit of time. Ingredients: 51 feet of ladder line an SO-239 or a piece of coax with a PL-259 a soldering iron & solder a tape measure Patience I used the SlimJim/JPole calculator at https://m0ukd.com/calculators/slim-ji... if you want to make your own.
