To my surprise he distrubutor sent me 3 for the same price. One set has just been installed into the lid of my ton "Oskar" :-) I think 15 kV rms will be the absolute limit , i will see. For higher power (on VLF) i will need to mount it into a larger plate which has to be mounted on the lit then. Unfortunately it is not water proof, see the images. I hope to fix that by using a 2 component glue. Oskar will carry the loading coil with a maximum of savety and security. https://dl.dropboxusercontent.com/u/19882028/VLF/20160501_190737.jpg https://dl.dropboxusercontent.com/u/19882028/VLF/20160501_190608.jpg https://dl.dropboxusercontent.com/u/19882028/VLF/20160501_190554.jpg 73, Stefan
