The Slim Jim Antenna
The Slim Jim is a vertically polarized omnidirectional end-fed antenna
having considerable "gain" and this is concentrated almost parallel to
ground toward the horizon rather than skyward making it more efficient
than a ground plane type antenna by about 50 percent better. It can be
built for almost any frequency!

( Below 10 meters it gets VERY tall )

Due to it's SLIM design, there is very little wind loading.
It is fed with 50 ohm coax.

** Now thats a new one on me. Is "Slim Jim" a generic slang term for the
** appearance of the antenna or a manufacture name?
