For those radio amateurs experimenting with antennas and feed lines, you may want to make a "Sea Water Antenna" similar to the one published by "SPAWAR Systems Center Pacific." The antenna is interesting if it works as presented.  Here's some more information from the company: "SPAWAR Systems Center Pacific has developed a technology that uses the magnetic induction properties of sodium chloride (salt) in sea water to create UHF/VHF/HF antenna." Even if the antenna doesn't work, you may have fun designing one and testing it out at the nearest lake or ocean beach. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Thanks to Greg Alexander for this thorough discussion on how to design, build, tune, test, and use this popular HF antenna.  In this video, Gregg configures the Inverted V as a "fan dipole" antenna. Here are some of Gregg's observations: A video documenting the process of building a dipole. How to build and tune a 40 meter Inverted V wire dipole HF antenna. Here I build a multi-band dipole antenna for HF use on 40-20-15-10-6 meters. Some call this a fan dipole. This is just a quick video of what I have setup for a 40/20 meter antenna. This antenna has been working very well for me in spite of how close it is to the ground. In a pinch it will even.
