Here are some comments from Mike (K8MRD):

This is a really easy, fun antenna to build. If you are new to Amateur Radio, or just want an easy to deploy 2 Meter antenna for out in the field, this is a great project. Here is the link to the antenna calculator I used. Be sure to scroll down a bit to see the diagram of the 70 MHz Slim Jim constructed with 450 Ohm Balanced Feeder. The build is the same, we're just changing lengths to make it for 146 MHz. I also changed the velocity factor to .9 https://m0ukd.com/calculators/slim-ji...
