Here's another fascinating antenna experiment from Kevin Loughin (KB9RLW).  In this video, we see Kevin's idea for a very broad range antenna--one covering 630 meters to 10 meters.  If you're stuck at home because of the coronavirus lock down, why not try a few antenna experiments?  Kevin's project looks interesting. Here are few of Kevin's comments: "The next antenna experiment has begun. I hope this one works out, it will be quite an interesting beast if so.

Here's another antenna experiment from Australian radio amateur Peter Parker (VK3YE). Material requirements for the antenna are minimal and cost is fairly low.  Peter explains: "Got 18 metres of wire, a couple of poles and not much space? If so this vertically polarised delta loop might work for you. It operates from 10 to 24 MHz and can give DX contacts. But is it directive? Watch the video and find out. PS: Like these videos?

Thanks to Josh of "Ham Radio Crash Course" for a most unusual antenna for the 20 meter Amateur Radio band.  Josh Nass uses his own invention to make getting on the air wonderfully simple and efficient--you just blow it up, make a few connections, and you're on the air. Here are some comments from the inventor: "This is an all-in-one unit. No radials needed. Just inflate the antenna, hang or mount it and get on the air.

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=gl_aByCV8KQ . This is post 2227 in a continuing series of simple ham radio antennas. Here's a handy and often necessary device to help you control common mode currents and other interference coming from a coaxial feed line. In this video, the "Radio Prepper" takes us step-by-step through the design, building, and testing phases of a simple RF choke.  Here are some of his observations: "For just a few Dollars to boot... An RF choke can save the day for field radio operations where you do not necessarily control all aspects of your antenna system and common-mode currents can wreck havoc on electronics, and even your fingers! Use an FT-114-31 with six turns of RG-174 or RG-316. You can also use eight turns with an FT-140-43. For more power handling you can use an FT-240-31 or FT-240-43 but I do not know the number of turns (RG-402). Do not

This is post 2226 in a continuing series of simple ham radio antennas. Thanks to Peter of "Waters & Stanton" for this excellent introduction to lighweight, inexpensive antennas for portable or emergency use. Here are some of Peter's observations: "HF Mobile whips can make great portable antennas. Maybe you already have some. A couple of single band models may cover your needs. Here we look at how to use them and the way to connect them up." ------ 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/ http://www.hamradioupdate.com. http://www.southgatearc.org. https://oahuarrlnews.wordpress.com. https://hamradiohawaii.wordpress.com. https://bigislandarrlnews.com. https://www.eham.net. h
