Generally one end of the wire is hoisted into a tree or similar support so it is somewhat
vertical. You can string it up in other ways as well. (Tie a weight on the end of a rope
and toss it over a branch and back down, and use that to pull the antenna up, or use
a fishing rod or slingshot. But don't try to toss the end of the antenna up into the
tree - it doesn't work as well.)
You do need a tuner of some sort because the impedance at the end of the wire is
a couple thousand ohms or so. Most tuners use a (variable) capacitor and a coil, which
can be hand-wound. Other approaches include a tapped quarter wave matching stub
like a J-pole (which is also an end-fed half-wave antenna) or a quarter wave of
My first 15m antenna was a twin-lead J-pole and it actually worked quite well.
Commercial units typically use a coil and capacitor for small size. You can make it
fixed-tuned for one band or variable.
