This is post 2109 in a continuing series of simple ham radio antennas. This intriguing, informative video from Kevin Loughin (KB9RLW) is part 2 of his experimental All-Band Doublet Antenna. In part 1, Kevin designed the antenna, selected his parts, and began assembling the doublet. In part 2, Kevin finishes his doublet antenna and tests it out on the air.  He makes several international QSOs, including one from Cape Town, South Africa.  Here are some extra notes from Kevin which may help you decide to build this multiband dipole antenna: "Thoughts and observations after using the doublet for awhile. Plus a couple of QSOs, one of which was stellar. Original design and build video: https://www.youtube.com/watch?v=tA4lo...

This is post 2108 in a continuing series of simple ham radio antennas. One of my favorite multiband HF antennas is the classic "All-Band Doublet."  The antenna is a basic 1/2 wave length horizontal dipole fed with balanced feedline going into a "balanced antenna tuner." In this video, Kevin Loughnin (KB9RLW) begins a two-part series on the theory, design, construction, and testing of this versatile, easy-to-make antenna. In part 1, Kevin looks at the antenna and its design before building the antenna.  In part 2, Kevin finishes construction and tests the doublet 's performance on the air. Here are some of Kevin's observations, along with links to helpful resources: "One of the antennas I've wanted to play with for awhile. In this video, we look at the antenna and it's design, and then my build of th

If you'd like to try some antenna experiments, then this video from the Mitsubishi Electric Channel will prove interesting. According to the presentation, "Our seawater antenna, named "SeaAerial," is changing the way we communicate. Rather than using metal, we've developed a more sustainable and flexible approach, keeping you connected to the things that matter most." Although I've never used this type of antenna, the idea seems intriguing.  At least the basic antenna material (i.e. salt water) should be cheap if you live near the seashore.  Why not build this seawater antenna and see how it works?  This could be a fun project. ------------ For the latest Amateur/Ham news and information, please visit these web sites: http://www.Ha

If you want a 160 meter antenna that "really gets out", try this balloon antenna launched by AK7AZ during the 2011 CQWWDX-SSB Contest. In this video, N7SCL takes us from unpacking the antenna package to the final assembly and launch of this "monster" vertical antenna. A grand time was had by all.  I need these guys for my next ARRL Field Day experience!.
