Cable RG number又是什么？谢谢

  RG means "radio guide" and was the original military

  specification for coax cable, starting in the 1930s. So what do

  all the numbers mean ? RG-6, RG-8, RG-58, RG-59, RG-62, RG-122,

  RG-213, RG-405 and on and on?

  The number is just a page in a book. RG-1 was the first page

  (and obviously wasn?t a very successful cable design). RG-6,

  the sixth page, was wildly successful. Most CATV/broadband

  cable these days is RG-6.
