A new transformer will be incorporated into new\/old \u00a0EFHW antenna models EFHW-8010-HP and EFHW-4010-HP as well it will\u00a0be sold separately for those who want to make their antennas for use out of HAM frequencies for\u00a0their needs such as MARS, Marine or EMCOM activities.<\/p>\n<p>New models can be seen at these links <a href=\"https:\/\/myantennas.com\/wpproduct\/efhw-8010-hp\/\">EFHW-8010-HP<\/a> and <a href=\"https:\/\/myantennas.com\/wpproduct\/efhw-4010-hp\/\">EFHW-4010-HP<\/a><\/p>\n<p>Also, see this short video of testing the antenna with a\u00a0new transformer at 1500W.<\/p>\n<p>73 Danny Horvat, N4EXA aka E73M<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"980\" height=\"552\" src=\"https:\/\/www.youtube.com\/embed\/TurdgZ7BWC8?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><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It has been a\u00a0long search for suitable materials and quite a few experimenting has been done to design a high ratio (~50:1) transformer for EFHW antennas capable of high power (1500W ICAS).
