I&#8217;ve never had a need to try one&#8230;..until now! There is some documentation out there praising this antenna&#8217;s low noise capabilities. So, it\u00a0was time to find out for myself and start building an experimental version. So far, the results have been really quite pleasing!<\/p>\n<p>I have prepared a YouTube video (below) in which I discuss the reasons for looking at this antenna, its design, and its installation. I also do some on-air comparisons of my experimental rectangular (!) version of the horizontal loop against my three regular double bazooka (coax) dipoles and the Par SWL End-Fed antenna.<\/p>\n<p class=\"p1\"><span class=\"s1\"><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/OLq3nBQppqg?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/span><\/p>\n<p>Have you tried this antenna before?
