Hi Curt,
the link you followed is easier to click, if the blank in the name is replaced by %20:

The strike target is simlply a stack of 3 big ceramic insulators, topped by a copper tube "antenna". The bottom end was mounted on an aluminium disk, which is not grounded. You can see it (without and with sparks) here:

specifically:

it's nice, to observe the sparks, spreading from the bottom disk to the floor:

I followed a link to a photo of Kurt Schraner's coil.
I see a really cool strike target on the left that
makes a good show of it's own.

Anyone have details of it's construction?

Curt.

Hi Gomez,

perhaps no need to scrap the coax idea. For my big
B&W coil I solved
the problem by adding 2 series power resistors.

please see

BTW: the braid of the coax should be shown grounded.
Please view in fixed font.

Best regards

Kurt

I guess I will have to scrap the coax idea, unless I strip the
shield off, but the shield was half of the reason for using it - I
wanted to protect against secondary strikes to the HV lines from
the NST filter - "defense in depth"!
