(Made from old J pole antennas using "HamEngineering")
Well I got the Slim
Jim built. Does not look like much as I used what I had.
It is up on the tower at about 50'. On the ground (11' up) the
SWR across the 2 meter band was less than 1.5:1.
The Slim Jim antenna is a total of 59" long top to bottom, with a 2 1/8 center to center spread between the copper. I used PVC to keep the spread at about 2 1/8". I forgot to measure the gap, but it was around 1 1/2".
Testing it out.......I
started with approx. 2 watts on a HT. I was able to "talk" on
repeaters at an air distance of 35 miles. Some noise, but very
readable. At 50 watts on a mobile, full quieting. I did a lot
of testing with the 2 watt HT with the antenna 11' off the
I'm really impressed with this antenna.
Like I said, this antenna was pieced
together using 2 old J poles. I ended up having to lengthen the Slim
Jim, so I used copper tees. That's all I had and they worked
Editor note. Although Bill reminds us that the finished antenna "does not look like much" we think ANY antenna is a beutiful work of art! And as a bonus, he loves it!
