Thanks to Dan Vanevenhoven (N9LVS) for this good, basic introduction to the theory, construction, and use of ground radial and counterpoise systems for vertical HF antennas. The ground radial/counterpoise system provides "the missing half" of a vertical antenna and allow it to be more efficient and stable. Dan does a good job of comparing a ground radial system for an AM broadcast tower to a simpler radial arrangement for an amateur/ham radio vertical.  For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.blubrry.com/arrlaudionews/ https://oahuarrlnews.wordpress.com. https://hamradiohawaii.wordpress.com. https://bigislandarrlnews.com. https://www.eham.net. http://hamradioupdate.com. http://www.southgatearc.org.

If you live on a large piece of property and want to explore the fascinating world of 160 meters, you may find this extra long antenna interesting. Thanks to Bob Holowenko for showing us his winter 160 meter antenna. According to Bob, this antenna is a real powerhouse on the "Gentlemen's Band." Here's how Bob describes his antenna: "1000ft of 14ga AWG wire (7-strand) and some rope make one of the best performing antennas I've played with. This is made from 127ft of vertical wire, 6 127ft radials, and a pile of random wire, including a fence, make for a fun little antenna." For your convenience, here's the conversion from feet to meters: 1000 ft=304.87 meters. 127 feet=38.71 meters. ------------------------------ If you have room on your property, you may want to build one of Bob's 160 meter an

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=IrWLqixFFuc This video from "learnelectronics" takes us step-by-step in the assembly, tuning, and use of the popular Hustler 4BTV HF Antenna.  Please note how carefully the antenna is laid out prior to assembly and how protectants, such as anti-seize compound, are used to protect joints, screws, bolts, and nuts. A carefully planned assembly routine is vital if you hope to build this antenna right the first time.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=KbFN78mrALQ. One of my favorite online video programs is "Ham Nation."  The 1.5 hour program covers a variety of Amateur/Ham Radio-related topics, including news, propagation, antennas, DX contests, and technical questions. In program 428, we get an excellent tutorial on "How To Moonbounce"--something that can be done with modest equipment and homebrewed antennas.  The discussion is clearly presented and is easily followed. Here are some of the other topics covered in this program: "YOTA Camp, equipment for moonbouncing. The Leonid Meteor Shower with Gordo, the AM band with George, Youth on the Air Camp at the Voice of America Museum with Neil Rapp and Jocelyn Brault, Amateur Radio Newsline with Don, Moonbouncing with Val and Lance Collister, your questions with Amanda and more! Hosts: Bob Heil, Gordon West, George Thomas, Don

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=bXp7uin7_7Y. Over the past few years, I've found an antenna analyzer a most valuable tool for designing, building, and using homebrew antennas.  Although my MFJ-259 is several seasons old, it does what it's supposed to do. In this well-made video from Ron Payne (WA6YOU), we get an excellent overview of what an antenna analyzer does and what are some of the shortcomings of the commercial products available. This presentation was given before members of the Vienna Wireless Society on 28 April 2017. Ron does a good job of explaining antenna analyzers in simple, easily understood terms.  As you may expect, there are several commercial versions of this useful tool available through the internet or from local Amateur Radio stores.
