Re: FDC cableing



Hi Joe, Gerard, Dave and Elton,

One more suggestion?

I suggest we get a full picture from the manufacturer regarding their 
design criteria for the electrical and non-electrical specs before we 
start designing a new version of the cable. I am not convinced that 
removing the braid will improve things. After all, we have space and the 
metal in the braid is a small fraction of the total material, right?.

I also concur that whatever we order must be in the final design 
configuration.

Regards,
Fernando
