Re: FEA of new rotary spark gap



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

I can't see any reason why a good RSG couldn't be made using a metal disk to hold the electrodes; it would be fitted with an insulating hub which wouldn't have very much stress in it (particularly if the disk were made of steel) and there should be some significant heat sinking to the disk. There were certainly gaps made that day in "the good old days of wireless" and they would certainly get around the problems of expensive materials. Any thoughts?
