Putting up a Wire Antenna
Ever wonder how to get a wire antenna up high enough to do anything of value? Many amateurs may climb their tower, or build a slingshot, or have the raw muscle to throw a rope into a tree. Maybe they use a telescoping mast or pole to get it to its ideal height. But many amateurs want a fast and simple solution. Here are some projects and guides to putting up a wire antenna.
- "The W4SSY Spudgun" QST, March 2009 p. 67-69 A guide to making a line launcher based on an air-cannon. Build it with simple componets often found at the nearest hardware store, and have a tool that can send up your antenna as high up as you need.
Dipoles
The most popular HF antenna for hams with trees to use as antenna supports is the dipole.

QST November 1995, pp.22-24
A traveling-wave antenna offers some attractive qualities for your station: 50 ohm feedpoint at ground level, no tuner required, horizontal and vertical radiation components, no radials, nothing in the air but wire, and flexible size and height requirements. - Zip-Cord Antennas - Do They Work?
QST March 1979, pp. 31-32
Parallel power cord is readily available and is easy to work with. How efficient is it when used at radio frequencies? Well, that depends. - The N4GG Array
QST July 2002, pp. 35-39
A simple, nearly invisible, multiband wire antenna with reasonable gain, low angle of radiation. - A High Gain Single Wire Beam by Robert Wilson, AL7KK

The author now recommends feeding this antenna directly with a 4:1 balun instead of the shunt inductor arrangement suggested in the article.
