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 [ Ссылка ] if you want to make your own.
