If you need a simple, inexpensive, and easy to erect HF antenna for Field Day or any other portable operation, you may want to use this idea from Larry (WD0AKX). Larry says he wanted to experiment with a random length wire in his backyard using QRP power and a portable set up to see what he could do with a minimum of equipment.  You will need an antenna "tuner", a 9:1 unun, and a ground radial/counterpoise system to make the antenna work properly.

HF random wire antennas can work very well as portable or emergency antennas if you pay attention to some of their limitations.  In this video, WD0AKX experiments with a random length antenna in his back yard.  Coupled with the internal antenna "tuner" of his Elecraft KX3 and a simple ground radial system, he found the easily made wire antenna produced several good contacts. WD0AKX supplies a few helpful links, including one which suggests workable antenna lengths for random wires (http://udel.edu/~mm/ham/randomWire/).
