Although Raymond Jackson (KB9COL) became a silent key in 2018, some of his excellent antenna tutorials remain popular.  His original design for a "6 Meter Plus Antenna" remains a favorite of many radio amateurs pursing contacts on "The Magic Band." Mr. Jackson's relaxed presentation and his clear explanation of the theory, construction, and use of this simple antenna make this video an attractive choice for a ham club meeting or an amateur licensing class. Here are some general comments about the antenna: Raymond Jackson ( kb9col ) is showing how to build your own 6 METER PLUS antenna. This is a great step by step instructional video.

Thanks to John (KB2HSH) for  a trip down memory lane with the "Eggbeater Antenna."  I remember many radio amateurs using this design to receive the down link for some of the early amateur radio satellites. This antenna is an excellent, easily-made omni-directional antenna for both home and portable us. John does an excellent job of explaining the materials, assembly, and testing of this near-"classic" antenna. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Although this video from GM0SDV is exceptionally made from a visual point of view, it suffers from a lack of an audio track. Despite this minor issue, the antenna is a prime example of excellence to detail and professional exactness.  Here are some of GM0SDV's comments: "Super Screwdriver antenna Build by antenna engineer :coil diameter 82mm whip 1.5 meters long working from 3,5Mhz to 54Mhz with SWR less than 1.2 Tested on several contest and DX very good results was (sic) achieved" ----- Good luck to all radio amateurs participating in the 2020 ARRL Field Day! ----- For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.Hawaii ARRL.info. http://www.arrl.org. http://www.hamradioupdate.com. http://www.southgatearc.org. https://bi

Do you need an simple, easily deployable HF Vertical Antenna for the ARRL Field Day? Then, try out this idea from Juddie (WD8WV). The antenna is highly portable and suitable for both field and home use. Here are some general remarks from Juddie (WD8WV: "This video is a short demonstration of a homebrewed vertical antenna using a inductive coil that I made. It somewhat resembles a Wolf River Coil. I didn’t record video or pictures of me building it, wish I would have.

If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=A_0-jBKGNTs This is post 2273 in a continuing series of simple ham radio antenna. How about trying a different antenna for the ARRL Field Day or for that next portable operation?  In this video from the "Ham Radio Concepts Channel", we see what one ham radio club used to raise its vertical antenna--A balloon-supported long wire over a river.  The antenna worked very well. Here are some general comments from the site: "We made a long wire vertical antenna suspended from a helium balloon over the river, at 25 watts and an MFJ 993b autotuner to tune it on 40 meters at field day 2016 at the Wabasso causeway north of Vero Beach Florida. It was a successful antenna and worked very well at around 25 watts." ----- For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http:

How I use my drone to deploy my wire ham radio antenna

Image
Have you tried using a drone to launch your wire antennas? Pat (N3GWX )has used drones to launch his HF antennas easily and efficiently. This is post 2272 in a continuing series of simple ham radio antennas. Here are a few observations from Pat as well as a list of equipment needed to launch your HF antennas to the tops of the tallest trees. Check out the view from above! Here is the drone setup I use in order to deploy wire antennas on the ham radio. I drop a weight via remote release on my drone, then pull a polypropylene slick rope through the tree and then attach the wire antenna and pull it up.

Thanks to N9YO of "HamRadioCQ.com" for this alternate way to launch your Field Day Antenna into trees. According to N9YO, this launching device is patterned after an arborist tool for launching lines over trees for climbers. Here are some of N9YO's comments: "This is how to get an antenna into a tree really high. Forget antenna towers. Why not use trees?
