Steve, I'd like to know more about the "copper/aluminum" center conductor. Does that specification mean that it may be either copper or aluminum, or that it is copper-clad aluminum? Either way, I wouldn't touch this stuff! If the manufacturer is not a qualified supplier of Military-Specification coaxial cable, I don't waste time or money on their products.

Does anyone have any experience or info on this coax good or bad? Below is the info on it. I'm looking at buying a spool or so for a group where I live to divi up. Will use mostly for household VHF/UHF base service.
