If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=wdrIOKXF7jE.  This is post 2254 in a continuing series of simple ham radio antennas.

Much of what I learned about communications and antennas came from my service in the USAF.  I used that knowledge to work in the broadcast field for 40 years and to secure my Amateur Radio License.

It's good to see some of the outstanding military communications videos brought back to life by Matthew of "Military HF Radio."

This video is part 5 of an excellent tutorial on HF communications and HF antennas.  The video covers a lot of antenna theory, construction, and testing in just over a half-hour.  The discussion of the T2FD (terminated folded dipole antenna) is especially noteworthy.

This video would be excellent for amateur radio licensing classes or amateur radio club meetings.

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=l91JL2ImEbk.  This is post 2252 in a continuing series of simple ham radio antennas.

If you need an excellent receiving antenna for HF and MF bands, then you can't beat the "classic" Beverage Antenna from the early 1920s.  Although significant space is needed to deploy this antenna, the rewards are great.

In this expertly done video from Steve (VE6WZ), we get a full tutorial on the theory, design, construction. and use of the Beverage Antenna.  Here are some of Steve's comments:

"Various methods for construction and installation of a Beverage RX antenna in the field. Described are methods for wire layout, tree clearing, wire support and both feed-point and termination installation using tree supports. Also shown is how the relay boxes for multiple Beverages, and the broadside phasing boxes are deployed in the field."

It doesn't take a lot of money or equipment to get on the air for the upcoming ARRL Field Day or for portable operations.

In this video from Johnny (W5KV) of the "Signal Search" youtube channel, we see how only a few components can put you in touch with radio amateurs worldwide.  Why not make this simple antenna for ARRL Field Day station?

Here are some of Johnny's comments:

"In this video, we'll discuss how to construct a dipole antenna for Amateur Radio using 50 ohm coax, a cutting board, and some simple hardware. Amateur Radio doesn't have to be an expensive hobby. 73 de W5KV."

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=tA4loiihJwE.  This is post 2247 in a continuing series of simple ham radio antennas.

One of the best all-around HF antennas is the multi-band doublet. The antenna is simple, inexpensive, and covers several HF bands with the aid of a parallel feed line and a balanced antenna "tuner."

In this well-made video, Kevin Loughin (KB9RLW) presents a two-part series on the theory, design, construction, and use of this versatile antenna.

Here are some of Kevin's remarks:

"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 the antenna. In part 2, we'll look at it's performance and try it out on the air. Link to web site mentioned in the vid: http://webclass.org/k5ijb/antennas/Al...

Here's another great, inspirational tutorial from the "DX Commander" (Callum-M0MCX).  If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=fbOY3OADpo8. This is post 2246 in a continuing series of simple ham radio antennas.

The classic "Fan Dipole" antenna is simple, inexpensive, and fun to build.  Callum describes how to build and configure this versatile antenna for your ham station.

Here are some of Callum's observations:

"Grab a coffee, sit back and enjoy. Buying wire antennas is such a waste of time when you can easily achieve remarkable results with a fan dipole. You can go inverted V or flat top, have as many bands as you want, there's no restriction. I discuss the problem getting 40m and 15m working together and explain why there is no limit to the number of dipoles you can build off one feedpoint. And of course, you can also build a "maypole" style as well, I sh…

The 2020 ARRL Field Day will be different, thanks to the restrictions imposed by COVID-19.  Many radio amateurs in the U.S. will be operating at home or in very remote areas under limitations imposed by local, state, and federal officials.

This doesn't mean you have to forego the experience just because you're locked down at home.  This is the perfect time to experiment with antennas and build some "skyhooks" for future operations.

Josh Nass from the "Ham Radio Crash Course" youtube channel has assembled an excellent, well-paced tutorial on portable ham radio field antennas for your next radio contest or ARRL Field Day.  This video was shown at a recent meeting of the Crescenta Valley Radio Club.  Keep a copy for your reference library.

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=qbje13U6hC4.  This is post 2242 in a continuing series of simple ham radio antennas.

Thanks to Claude Jollet (VE2DPE) for this easily understood video on how to build a six meter folded dipole antenna.  Although the tutorial is quite clear, I did miss a spoken audio track.

According to Claude, materials for the project are simple and easily obtained:

"A ham radio six meter folded dipole antenna made of ladder line, fed with ladder line and matched with a step down 4:1 coaxial balun at the bottom of the transmission line. Cut to resonate at 50.4 MHz. SWR is below 1.3 between 50.0 and 51.0 MHz."

MFJ Duplexer-two radios one antenna or vice versa

Image
If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=i9ttJn7Qy_s.  This is post 2239 in a continuing series of simple ham radio antennas.

Here's a handy device from MFJ that allows two radios (2m/70cm) on one antenna and vice versa.

David Casler (KE0OG) does a good job of explaining the theory and use of this useful tool.  Here are some of his remarks.:

"A look at the MFJ-916B duplexer with SO-239 connectors (also available with N connectors and also available with an outdoor version). You can use this to connect a 2m radio and a 70cm radio to share a single, dual band antenna, or use it with a dual-band radio to connect to a separate 2m antenna and 70cm antenna.
