  1. Hope you can translate English, have built this 'short 40M' vert. in my rear yard, with three 10M radials. It seems to work very well and is very quiet! One question please! Is the diameter of coil former 5.8cm or 5-8cm? I used 34 turns round 5cm plastic pipe, and when tuned on a communications set it gave most back ground noise nearly dead on 40M! So I presume it's okay. My 'short 40M vert.' is just 12cm above ground at feed point. I have worked 750KM north of Moscow on about 150W, one evening on 40M,from Dover England,and even good for local stuff within UK! Brian M6BAQ
