This is post #1311 in a continuing series on Simple Ham Radio Antennas. Experimenting with magnetic loop antennas is fun, educational, and often rewarding, especially for radio amateurs living in deed-restricting homes, apartments, or condominium units. In this video, Kevin Loughin (KB9RLW) creates a working magnetic loop transmitting antenna from parts he found in his ham shack.  Despite some limitations, the antenna works and serves as a template for further magnetic loop designs.  Perhaps, this video will encourage you to build your own antennas.

New product for antenna testing (http://www.sotabeams.co.uk/wsprlite-flexi). Accessed on 13 November 2017, 0125 UTC. Author:  SOTABEAMS. Please click link to read the full article. Comment: On Saturday, 11 November 2017, UK antenna manufacturer, SOTABEAMS, announced the release of a new antenna tuning system called WSPRlite-Flexi. According to SOTABEAMS, the new antenna device covers from 6 meters through 630 meters--just right for radio amateurs experimenting on the 630 meter band (472 kHz to 479 kHz). Here are some of the features of the Flexi System: "The Flexi also incorporates a number of new facilities including a unique interference avoidance algorithm to help it avoid interference from other WSPR users. When combined with the  DXplorer.net  website, WSPRlite provides a unique way to look at antenna performance and to see how propagation varies in real-time.

Here's a simple, cost-effective, and easy to build HF receiving antenna using parts found in your ham shack or at the nearest building supply or home improvement center.  For those radio amateurs living in deed-restricted apartments and homes, this compact, lightweight antenna can be used to receive shortwave and ham radio signals without upsetting your neighbors.  The antenna is highly directional and can be used to sidestep noise and interference in your home. Although this loop is not designed to be used with transmitters, it can give your some flexibility in your receiving antennas.  You could always design and build a transmitting magnetic loop antenna to complement this receiving antenna. You then would be totally "stealthy". For the latest Amateur Radio news and information, please visit these websites: http://www.HawaiiARRL.i

The K3MT Grasswire HF antenna designed by Mike Toia (K3MT) may be the ultimate stealth or portable antenna. You lay the antenna on the ground and start operating.  The antenna is nearly invisible. In this video from AC2RJ (rcobo 101), we see how simple and effective this antenna is.  AC2RJ says he laid out 100-feet/30.48 meters of speaker wire on the ground of his backyard and quickly got contacts on 20 and 40 meters.  An antenna "tuner" and a decent earth ground, radial system, or a few counterpoise wires will improve the efficiency and performance of this emergency antenna. You can find Mike's original article by checking the left hand column of this blog under the "pages" section.  Mike gives you all the theoretical and practical construction tips for this antenna.  If you follow Mike's instructions, you'

Here's part 2 of an 80-6 meter OCF Dipole Antenna created by "Survivalist2008". In part 1, we collected the materials for the project and began construction of the antenna.  In part 2, we put the finishing touches on this antenna, erect it in the field, and make some contacts. The antenna is lightweight, stealthy, and compact. You may want to make one for your next portable or backpacking operation.  You could always use this antenna to back up the antennas you now use at your home station.
