Here's another entry in the growing availability of compact HF magnetic loop antennas.  These antennas can help those living in deed-restricted areas (HOAs and CC&Rs) get on the air without undue suspicion from neighbors.  This antenna comes from LNR and covers 60 meters through 10 meters, with an option to cover 6 meters in the future.  This video shows you how to set up and operate this portable HF antenna.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=ir51s_PbJfg. The Ham Nation program on the TWIT network is one of my favorite programs because of its relaxed style of presentation and the offering of valuable ideas for a variety of amateur radio projects from antennas to operating aids. In this program (episode 266), Dr. Bob Heil, Gordon West, and Don Hill discuss the theory, design, construction, and use of coaxial dipole antennas for both HF and VHF/UHF use.  The explanations are easy to understand and should give you some ideas if you wish to build one of these antennas.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=3j3BsYbzwvw. If you want up to 3dB gain broadside to your current HF Dipole Antenna, consider building an Extended Double Zepp Antenna.  According to Stan Gibilisco (W1GV), the EDZ Antenna is a "collinear array of two 5/8 waves in phase." In this video, Stan reviews the theory behind this classic antenna, how to build the antenna, and what kind of feed line is required to make the EDZ work properly.  You will also need a balanced "tuner" or a "tuner"/balun combination to get maximum efficiency from this design.  Also, you will need more room for the antenna elements, especially if you make this antenna to cover Amateur Radio bands from 80 to 10 meters.  You may find the gain worth the effort in making this unique HF antenna.

Helical Antenna for the 20-meter band, Post #1430.

Helical Antenna for the 20-meter band http://www.antentop.org/017/files/va3znw_017.pdf Author:  Igor Grigorov (VA3ZNW). Accessed on 13 March 2018, 2105 UTC, Post #1430. Please click link to read the full article. Comment: Thanks to Igor Grigorov (VA3ZNW) for this wonderful idea for a small, easy-to-tune 20-meter helical antenna which can be used on all amateur radio bands from 40 meters to 10 meters with an antenna "tuner."  Igor says this reduced size HF antenna works well, considering its dimensions.  The antenna is also "stealthy" and won't attract the attention of neighbors. The article provides a good step-by-step tutorial on how to design, build, and use this antenna.  Igor's article contains several well thought-out steps: Materials The importance of grounding and ground radial systems Tuning and adjusting the antenna Schematics and diagrams of the antenna Antenna "tuner" requirements For the latest Amateur Radio news

If you can't see the video, please insert this title URL into your browswer search box: https://www.youtube.com/watch?v=sU9iBLeuTXs. The new military 2.0 multiband tuner free Alpha Antenna is good, practical HF antenna for portable or emergency use.  According to "videosbymike" the antenna doesn't require an antenna "tuner" and easily covers the 80 through 10 meter Amateur Radio bands.  This video does an excellent job of showing how to unpack, assemble, mount, and use this versatile HF antenna.  In this video, portable, foldout solar panels and a solar panel controller provide the power, while a simple tripod holds the antenna in place.
