Hi Stefan

The cable should be left "fl= oating" whith any HV picked or I can even connect it to a gas discharg= e tube to GND

The loop is not completely horizo= ntal. It is about 4m higer in the north, than in the sides and south. May b= e it affects the radiation
pattern a bit. But there are (sti= ll) not so many monitors with good Rx to confirm this

Hi Luis,

BTW. Those 24kV at 800 W can expl= ain some pictures shown in this reflector ;-)
I know someone who has up to 45 kV rms on his LF antenna... 
 
Will test it at low power first a= nd see what happens. Think I can measure induced voltage on motor coils and= this will show the risk of increasing power
Can't you remove the cable of the motor so it is floating at high potential= too?

I'm still in the process of getti= ng access to the fire extiguish pipe to clamp a wire up to the antenna. It is not easy, but can be done
That sounds fine!
