The discussion of RG-214/U coaxial cable prompted me to take a look at the current military specifications, and I was surprised to note that a "new" version of RG-214/U cable has arrived. This new version has a one-mil thick polyester tape with an aluminum coating that wraps around the outer shield, with the aluminum side in contact with the silver-plated shield.
I have just created a folder in the Files section of this list, entitled Coaxial Cable Specifications. The Military Specification for RG-214/U cable is MIL-C-17/75F. There is also a copy of Amendment 1 to that specification, which makes it inactive for new design and shows RG-214 to be replaced by M17/190-00001. I included a copy of that spec, as well. One might wonder if the "new and improved" cable is more prone to PIM from dissimilar metals than the original. I intend to upload several other specs soon, including RG-58, RG-213, RG-142, RG-400, etc. Stay tuned... 73, Eric Lemmon WB6FLY
