The K3MT Grasswire HF antenna designed by Mike Toia (K3MT) may be the ultimate stealth or portable antenna. You lay the antenna on the ground and start operating. The antenna is nearly invisible.
In this video from AC2RJ (rcobo 101), we see how simple and effective this antenna is. AC2RJ says he laid out 100-feet/30.48 meters of speaker wire on the ground of his backyard and quickly got contacts on 20 and 40 meters. An antenna "tuner" and a decent earth ground, radial system, or a few counterpoise wires will improve the efficiency and performance of this emergency antenna.
You can find Mike's original article by checking the left hand column of this blog under the "pages" section. Mike gives you all the theoretical and practical construction tips for this antenna. If you follow Mike's instructions, you'll have an excellent portable antenna that can get you on the air quickly without raising the ire of nosey neighbors.
