Hello all,

I wash to busy to rebuild my C31XR insulators. The 20m reflector insulator 
wash burned while transmitting on 160m.
Greg how did you ground the elements inside a stepper ?
I'm replacing my tower next year and thinking to ground my reflectors and 
driving elements
of my c31xr. Anyone  did that before ?

if you wanna see some pictures of the flashover see
