Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Electronics, published 1930-1988. All copyrights hereby acknowledged.

I'm always tempted to wax nostalgic over ads like this one since they remind me of more care-free childhood and early teenage years when our household had the typical single television set with an antenna on the roof and a 300 Ω twin lead cable running haphazardly down the roof surface and over the metal gutter, stretching under the eave to where it was crushed between the window sill and lower window pane, and snaked along the wall and floor to the TV. In the early days, our antenna was fixed (no rotator). Situated in Mayo, Maryland, about midway between Baltimore and Washington, D.C., where our nearest broadcast stations resided, we somehow managed to get acceptable reception on our low-end black & white television. I don't recall in which direction the antenna was pointed (maybe northwestish to cover both directions equally). It wasn't until sometime in the early 1970s that we finally got our first color TV that the system showed its weakness. The color TV signal is much more complicated and is more sensitive to low signal-to-noise ratio due to its more critical timing for voltage levels and phases. By about 1975, I had had enough and volunteered to put up a better antenna with a rotator and high(er) quality twin lead designed for color TV signals. It made a huge difference, and we were even able to pick up UHF signals that were never tunable before.

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...
