This video from "campindave1" show the step-by-step process of designing, building, and operating a multi-band HF dipole for the 2013 ARRL Field Day.  Members of the Owatonna Steel County Amateur Radio Club take you from the basic materials to the finished product in a few short minutes.  Simple, easy-to-build HF dipole antennas can perform very well if they are at least 1/2 wavelength above ground.  This video does a good job of showing the actual building process.

Comment: If you have a limited area to erect a multi-band HF Dipole Antenna, you may want to consider this vertical HF dipole antenna from DJ0IP. The illustration provided by DJ0IP provides all of the information you need to design, build, and operate this simple, elegant design. Here's the list of  basic materials for this antenna: A telescoping fiberglass antenna mast 12 meters/39.36 ft long.  DJ0IP uses a Spider Beam fiberglass pole to support the antenna. 6 meters/19.68 ft of wire for each antenna element for a total of 12 meters/39.36 feet. A homemade antenna center insulator.  Each antenna element is wrapped in a loose spiral for each half of the fiberglass pole. A convenient length of 450 ohm open wire feed line. A balanc

N9SAB Half Square Antenna-Field Test. Post #1476.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=_JR9v0YeI. Excellently presented test of N9SAB's 20 meter Half Square Antenna by "Outdoors On The Air."  While the half square antenna is a bit more complex than a simple random wire or dipole, it does show some gain (around 3dB) broadside over a dipole antenna.  In this video, "Outdoors On The Air" assembles, erects, and uses a half square antenna built by N9SAB, and shows the DX capability of this phased vertical array despite being only 20 feet/6.097 meters above ground. While the antenna can be erected by yourself, you may need some help to make sure the antenna elements are properly supported and aligned.  Although the half square can be used in portable operations, it may be best suited for a permanent installation. Over the past several years, the Big Island Amateur Radio Club (Hawaii Island) has used half square antennas fo

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=QbbMPID2ItA. Here's another great antenna for portable or emergency HF operations, including the upcoming ARRL Field Day on 23-24 June 2018.  In this video, Julian (OH8STN) does an exceptionally fine job of showing us how to assemble, configure, and use the "Super Antenna MP1DXMAX."  This rotatable horizontal dipole offers excellent directivity, something that will prove useful during contests and portable operations such as field days, camping trips, and SOTA (Summits On The Air) events.
