Rusty (N0KTZ) has done an excellent job of showing how to erect a portable HF antenna during a field outing in the mountains. His set up is simple, effective, and fairly stealthy.  Materials for his antenna launcher and wire holder are available at your neighborhood building supply outlet  You can't beat a simple slingshot, fishing line, and sinkers for launching your HF antenna above nearby trees.  You may want to practice with your slingshot before launching your portable HF antenna.  Rusty takes you step-by-step through the launch sequence.  Well-done video with many helpful suggestions.

If you have trouble viewing this video, please enter this URL into your browser: http://youtu.be/642N0oWgY5I. A nice, simple tutorial from W0ZF on how to make an inexpensive portable vertical antenna for the 20 meter Amateur Radio Band. I've made a few of these antennas using a fiberglass telescoping mast, some #18 AWG speaker wire, a few insulators, a simple ground radial systems, an appropriate length of RG-8X coaxial cable as feed line, and an antenna transmatch (i.e. "tuner") to keep the SWR to a low level. If you wish multiband use of this 20 meter vertical antenna, you can feed the antenna with balanced line (450-ohm window line or 300 ohm tv twinlead). The balanced line would go into a 4:1 balun and then onto your antenna transmatch using a short length of RG-8X coaxial cable. This simple antenna works.
