October 1946 Radio News

October 1946 Radio & Television News Cover - RF Cafe[Table of Contents]

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

I'm not too proud or vain to admit that until I saw this advertisement in a 1946 issue of Radio News magazine, I did not know (or don't remember knowing) that "Amphenol" is a compact form of the American Phenolic Corporation. Phenol formaldehyde is the technical name for phenolic. Bakelite, the trade name for polyoxybenzylmethylenglycolanhydride, is probably the most familiar form of phenolic since it was used in many types of electronics for both enclosures and internal component boards and the components mounted on them, connectors, and more. Modern plastics, fiberglass, and resin compounds have replaced most or all phenolic components. This particular promotion is specifically directed toward amateur radio operators (aka Hams), who composed a fairly large fraction of the magazine's audience. BTW, Amphenol is one of the diminishingly small number of American companies still around going by their original name. Even more rare is that it appears to still be a U.S.-based concern.

American Phenolic Corporation, October 1946 Radio News Article - RF CafeAmphenol and Radio Amateurs Have Always Worked Together

Radio amateurs are the most versatile technical experimenters known - and so are Amphenol engineers. Amateurs have pioneered the greatest share of electronic developments since the dawn of radio - and Amphenol has pioneered in the development of components used by hams.

Amateurs have an appreciation of the electrical engineering problems in the production of components to give the best performance. They agree that Twin-Lead, pioneered by Amphenol, is one of the most important and useful new products in the field of electronics.

75 Ohm Transmitting Twin-Lead

Amateurs asked for it - now here it is! It's the new heavy duly 75 ohm Amphenol Twin-Lead transmission line. Conservatively rated at 1000 watts for 30 mc or lower frequency. Available - now - at your distributor's.

Receiving Twin-lead is available in 75 ohm, 150 ohm and 300 ohm impedances. Get a copy of Amphenol's new Twin-Lead bulletin from your dealer.

Other Amphenol products of interest to amateurs available at your dealer's:

Radio Tube Sockets. Industrial, standard, miniature and sub-miniature - plugs and accessories. Octal angle sockets for cathode ray applications.

Connectors. All types, with fittings - from 1 to 50 contacts.

Cables. Coax and Twinax (also connectors). Microphone cables (also connectors).

Plastics for Electronics. Plastic sheets, rods and tubes. Flexible tubing end spaghetti. Coil Dope. Molded coil forms, stand-off insulators, knobs and dial pieces.

Antennas. UHF dipoles and arrays.

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...
