The Slim Jim is another name for a J-Pole from everything I read about
it. This is a 1/2 wave antenna over a 1/4 wave matching section so
your 49 meter band antenna would be rather tall (about 37 meters).
Sure, you could make it ......... would be interested to see your
plans for installing it 8-}

The Slim Jim is basically similar to the J-Pole, as you describe,
but with a folded 1/2 wave section.
The J-Pole is basically a version of the original Zepp antenna, patented
in 1909, and designed to hang below balloons. The 1/4 wave matching stub
and the 1/2 wave radiating portion don't have to be inline, they can be
in a L arrangement with the top horizontal.
