2 Meter Amateur Radio Slim Jim Plan

Here are the plan I use for constructing and experimenting with Slim Jim antenna on 2 Meter VHF Amateur band. The measurement used are designed to center around 144-148 MHz radio frequency, which is used by amateur radio world wide.

FYI this is the plan that I use to construct my first ham radio antenna using PVC pipe and aluminium tube.

  • Hi,

    I tried out that 300Ω twin-lead variant of the Slim Jim mentioned on the site, and so far, it seems to be working great.

    You have a very easy to follow guide. Cheers for putting it up for the rest of us to see. :-)
