Thanks to Rich Rodgers for this simple, efficient way to install a ground radial system for an HF vertical antenna.
Here are some additional comments from Rich:
"How to install Ham Antenna Ground Radials in the ground.. This is a easy way of cutting a groove in your yard for antenna ground Radials. I used an electric edger. It took about 10 Minutes to cut the groove. You might want to use 6 in. x 1 in. x 6 in. Metal Blanket Staples you can find at a hardware store." ----- For the latest Amateur/Ham Radio news and information, please visit these websites:

This is post 2281 in a continuing series of simple ham radio antennas.
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. The Length of the 75 ohms coaxial cable " each " is 32 inches. This is from the tip of center " Male " ( Hot…

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.

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"

If you need about 11.5 dBI gain on the 2 meter Amateur Radio Band, then this antenna is for you.
Mike (M0MSN) takes us step-by-step through the building, testing, and use of this impressive VHF antenna.
Here are some of Mike's comments:
"The construction of a shop purchased, ZL Special 7 element Yagi antenna for the HAM Radio 2M band. This no frills antenna boasts a 11.5 DBd Gain, is simple to build and works straight out of the box (once put together). Great bit of kit at a good price. Brilliant :) Please subscribe..

Thanks to Callum (M0MCX) for this ongoing series of antenna tutorials.  In this video, Callum discusses some of the simple, effective antennas you can build at modest cost.  This antenna group includes dipoles, verticals, yagis, quarter-wave antennas, and 5/8 wavelength antennas.  
Callum's energetic and down-to-earth style makes antenna theory and practice understandable and fun.
Here are some of Callum's remarks:
"Ham Radio Verticals, Dipoles, Yagis, Quarter Waves and 5/8th. Let's take off the covers and look inside. Fun, educational and LIVE. So anything might happen! Callum. M0MCX."

This is post 2276 in a continuing series of simple ham radio antennas.
Thanks to Callum (M0MCX--the "DX Commander"), we have an excellent "wordless" tutorial on how to design, build, test, and use a basic doublet antenna.  The step-by-step procedure is so good that a verbal explanation isn't needed.  
Here are some general comments from Callum:
"A Visually Impaired Customer ordered this one-off-special with specific measurements to fit his tower and property. Made with regular 450 ohm Ladder Line, a Doublet Centre from HamTenna and DX Commander's own DX50 Kevlar Cored Antenna Wire. Enjoy. Callum. M0MCX."

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. DE WD8WV" ----- For the latest Amateur/Ham Radio news and information, please visit these websites

Thanks to OM0ET and OM0WT for this excellent example of a home made HF vertical antenna suitable for both home and portable us.  Most of the materials for this project can be found at online ham radio stores or the nearest building / housing supply outlet.
Here are some additional comments:
Hello! In this video I show you my homebrew multiband vertical portable antenna :) Me and Paul OM0WT went to try it in the field how will this antenna perform. We were impressed! We had many QSO's and two special - India! This vertical worked also with 100W without any problem :) All european QSO's we was made with 20-50W max. I plan to improve more my design and then show it again. I hope you enjoy this video! 73 and please subscribe if you like ;) #multibandverticalantenna#portableant…

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:

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:
