A couple of years ago, I bought solid copper conductor RG6 at Lowes. Yesterday, I found that all they had was copper coated steel. Home Depot also had only copper coated steel, although a salesman looked up the specs on their RG6 and the conductor was listed as "copper"; but when I scraped a section of the center conductor it was obvious it was copper coated steel. Buyer beware. I ended up ordering from SolidSignal.
