I noted the "simple" vertical half-wave dipole configuration on your site. Is this the type used in your test? Also, do you feel the choking is sufficient to "eliminate" the rest of the feed-; /archives//html/Towertalk/2013-11/msg00281.html (6,894 bytes)

(score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Fri, 15 Nov 2013 05:02:12 -0800; Given the choice, most would opt for an elevated vertical. However on 80mx and to a lesser extent on 40mx a ground mounted antenna on good ground can be an effective DX antenna. All of which is why I; /archives//html/Towertalk/2013-11/msg00290.html (9,874 bytes)
