[UK-CONTEST] UK-Contest Digest, Non-conductive ropes for guying

[Giles Herbert]

Off the top of my head and not thought through, can the lengths of wire that causes the problem be detuned as Les Moxon described by detuning?  This, it is suggested, can be acheived by adding a resonant loop at the frequency of interest without making any connection to the stay electrically.  This is described in his book. I have 12 glass insulators which are the sort without holes that are held in compression and would meet Ray Hill's description.  They are 2" long, by 1.5" wide.  If you would like to become the new owner, and one who might use them properly, please email me.  73
