Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

During World War II, the government created a specification for military-grade cable and assigned the designation RG-#/U, where "RG" stands for Radio Guide and the "U" stands for Utility. The "dash number" was sequentially issued and has no bearing on the characteristics of the cable. Founded in 1902 in St. Louis, Missouri, by Joseph Belden, the eponymously named company has been and continues today designing and manufacturing coaxial cable. Most of the RG-x/U coaxial cable types displayed in this 1951 Radio & Television News magazine advertisement are still being used today, in particular the very familiar RG−58/U (50 Ω), RG−59/U (75 Ω), RG−8/U (50 Ω), and RG−11/U (75 Ω).  RG−5/U (52 Ω) and RG−54/U (58 Ω) are hard to find nowadays, although all these types can be purchased through companies like Allied Wire and Cable.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
