Wire loop antenna on the ground for HF receiving-How good?

Image
  If you are plagued by local noise (RFI) or HOA complaints, you may want to try "the antenna you put down, not put up" built by Australian radio Amateur Peter Parker (VK3YE). Peter's wire loop on the ground may be nearly invisible to your neighbors while it reduces some of the bad noise in your area. Although the antenna is primarily for HF reception, it could, in an emergency, be be used a NVIS (near vertical incident skywave) antenna.

Here are some comments from Peter (VK3YE): A wire loop on the ground as a receiving antenna? How well does it work? Here I give it a test.

Using a below ground-level antenna.

Image
  During most of my "amateur radio" years, I've always preferred to erect my dipole antennas above ground when possible. However, there are times when a below ground-level antenna system is the only way to get on the air. In this video, Tracy (VE3TWM) shows how he designed, built, and tested his homebrew below ground-level HF antenna at a portable location.   Other than some pesky QRM, Tracy's antenna system worked quite well.  This is another great idea you can put into your future projects book.

Building Beach Antennas for Ham Radio

Image
  Thanks to Walt (K4OGO) for this interesting, somewhat curious HF antenna that is more powerful than you think. The key to the outstanding success of this otherwise normal vertical antenna is its proximity to the ocean and its moisture-laden sandy beach.  This combination makes for an excellent ground, which most 1/4 wavelength vertical antennas need for maximum efficiency. Walt does an excellent job of blending antenna theory with practical applications in designing an antenna which produces excellent DX contacts.

How to build a 2 meter Halo Antenna

Image
The Halo Antenna is a fascinating piece of Amateur Radio antenna art.  The design was popular with mobile and portable operators many years ago. In this video from Chuck (KK6USY), we get an excellent introduction to the theory behind the design and some practical suggestions on construction, testing, and use of this "classic" 2 meter antenna.

Here are some comments from Chuck (KK6USY): In this video I show how I built a halo antenna for the 2 meter band. I give dimensions and a close up view of the antenna at the end. m2 antennas, https://www.m2inc.com/FG2MHOLOOP Sal Electronics, http://sal-electronics.com/halo_anten... https://vk1nam.wordpress.com/2020/12/... https://qrznow.com/2-meter-halo-anten...
