Any experience with that? Would that do any good? End december 1999 I placed about 50% of the loading inductance at the top of the vertical section (remaining 50% at groundlevel). Result was a gain of abot 3 to 5 dB. I will try to get about 90% of the inductance at the top soon, let's see what that will do. 73, Rik ON7YD
