However, I did run into an antenna design that was significantly different
(to me, anyway) last month, in an old article about inverted-Ls by L.B.
Cebik. He showed an inverted-L fed at the transition from vertical to
horizontal. Open-wire line ran down and away from it at a 45 degree angle.
Basically, it's a dipole with one wire horizontal and the other wire
hanging down vertically, so no radials are required. It might be fun to at least model it, if not actually try one on 160 or 80 sometime. The vertical
portion would have to be bent and run parallel to the earth in some cases.
Anyone here ever try one like it on 160?

When the antenna is less than 1/2 wave long, and if we do not change the antenna configuration, we can move the feedline around in an antenna until we turn blue and the only thing that changes is feed impedance.
