A long time ago now I built a slim jim for 2m and 70cm using the design calculator found here: https://m0ukd.com/calculators/slim-jim-and-j-pole-calculator/ anyway all i had to check it was a cheap SWR meter and it kind of looked ok and worked ok. So today after putting it back in the air so I can use it, i figured that I should chuck it on the VNA and see what is really going on. Well, it looks rather ugly that is for sure but it actually works well enough and its not very high off the ground either. Maybe 4 meters. But i can open a bunch of local repeaters ok from the Gold Coast to Noosa and that is good enough for me.
