+I've built myself a common mode choke last winter (2022) but haven't created
+this page yet. Also I haven't used it much because I haven't been very active
+this year.
+
+So this is basically a 140-43 toroid with 9 turns of RG174 connected to
+BNC connectors.

+Beside some other little tryouts this is probably the first
+antenna that I built myself. It works without a tuner (depending
+on the actual position of the antenna).
+
+My first contact with this antenna was into Israel (~2629 km) with my
+older FT-891. It was contest time and I actually replied to a contest
+station because I thought nobody would hear me because of my crappy
+antenna but I found myself picked up by that contest station from Israel.
+
+The resulting report of _59_ would not mean anything but at least I knew
+the antenna was working just fine.
+
+I got a SWR of about 1:1 (1.02) when I measured the antenna in an L
+configuration -- approx. 1-1.5m above the ground.
