If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=a0hCtmbD5as. Here's a simple random length end fed HF antenna (with antenna "tuner") that will provide multiband coverage at little expense. With the exception of the transformer and some heavy gauge wire, you can find most of the antenna materials from the nearest neighborhood hardware store or building supply outlet. Bret of "Survival Comms" takes you step-by-step through the design, construction, tuning, and use of this versatile HF antenna.  Properly designed, an end fed random length antenna can solve most of your HF needs.

40 Meter Inverted V Antenna - Build, Tune & Test! Post 1906.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=tbq1UgwM_go. A nicely done video tutorial from Barbara Justice and her children on how to build, tune, and test a multiband inverted Vee Antenna.  According to Ms. Justice, this inverted Vee dipole is built like a fan dipole and is capable of working the 40, 20. 15, 10, and 6 meter amateur radio bands. The instructions are clear and the assembly is fairly easy.  It was good to see her children involved in making this simple, effective antenna.  Perhaps, the "younger set" will pursue their own amateur/ham radio licenses in the future.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BJ07Y-ScFoM. Here's a simple, efficient, and compact 2 Meter Antenna that would be perfect for home station use and any portable operation, such as the ARRL Field Day, SOTA, or IOTA expeditions. Matt from Tech Minds does an excellent job of showing how to assemble and test this great kit from moonraker.eu.

Field Day Antenna Launching Demonstration. Post 1904.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aCyyH0a_Cpk. One of the major issues facing ARRL Field Day participants is how to launch your dipole, random length, and end-fed antennas into nearby trees. In this video from the Maple-Newton Amateur Radio Club in Delaware County, Pennsylvania, we see how a homebrew compressed air cannon put this antenna farm into some tall trees.  You can find plans for such devices on the internet. While this air cannon certainly works, it requires a certain technical expertise to build one without endangering yourself and others. When I face the antenna launching problem, I take a simpler and perhaps safer route:  I use my trusty Walmart slingshot, some fishing line, a few sinkers, a long length of rope, and a sturdy antenna to put my dipoles and end-fed wires into nearby trees.  Whatever launch method you use, please consider safety first before you launch your ante

#285: Amateur Radio Field Day 2018 - my 5 watt setup with on-air contact...

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=f4xhfwTtiEU.  Post 1903. If you can't join your amateur radio club for the ARRL Field Day, why not go solo at the nearest public park or even in your own back yard?  You can enter as either class 1-D (commercial power) or class 1-E (emergency power). In this well-made video from New Jersey radio amateur W2AEW, we see a simple QRP station at work during the 2018 ARRL Field Day held at one of the original Marconi transmitting sites. The set up is simple, portable, and efficient:  an ICOM-703+ QRP transceiver and a triband end-fed wire. If you're really ambitious, why not make a tape measure yagi and work some Amateur Radio satellites on 2 m and 70 cm?  Field Day is for any licensed radio amateur, club member or not.  Have fun!

End Fed Half Wave Antenna -11 Bands One Antenna! Post 1902.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Ree8NtpEEW4. Great video from Steve Ellington as he shows us how to get 11 amateur bands from one end fed half wave antenna.  The key to this fascinating antenna is the 49:1 balun and the relay box.  If you bypass the relay box, you can add 160, 60, and 6 meters to the 130-ft/29.63 m antenna element. Although the project is a bit complex, your effort will result in an effective antenna which covers the major amateur/ham radio bands from 160 through 6 meters.

Building a trap dipole for 7 and 14 MHz. Post 1901.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=LbEAwAG1KMA. If you only want to operate on two or three bands and don't want to adjust an antenna transmatch (i.e. "tuner"), then this trapped dipole for 7 and 14 MHz may be for you.  Peter Parker (VK3YE) does an excellent job of taking us through the theory, design, construction, tuning, and use of this simple, effective antenna. Peter puts particular emphasis on getting a SWR closest to 1:1 and on designing an effective 14 MHz trap.  This project would be excellent for any "field operation", such as the ARRL Field Day, SOTA, or IOTA DX-peditions.
