About RF Cafe
Copyright: 1996 - 2024 BSEE - KB3UON 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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Channel Master Antennas Advertisement |
||
One sure giveaway to the age of a picture is the presence of a wheat penny, a buffalo nickel, or a Mercury dime. This 1957 advertisement for Channel Master antennas has all three. It shows a walking Liberty half dollar as well. Quarters haven't changed much over the years, with George Washington's head on the obverse side since 1932. The wheat penny design ended in 1959 when the Lincoln Memorial was put on the reverse side in its place. Thomas Jefferson's head has been on the nickel since 1938. Theodore Roosevelt's head was ensconced on the obverse of the dime in 1946. John F. Kennedy was placed on the half dollar obverse in 1964. This ad is about antennas, not coins, though. For a lot, if not most, of RF Cafe visitors, there has always been cable and satellite television. For some, TV has always been available on their smartphones. Everyone's concept of history begins when he/she is born. Those of us who grew up in the over-the-air broadcast world remember well the importance of having a good quality antenna, with a rotator, to be able to watch our favorite cartoons and prime time shows. We remember going up on the roof with our fathers to install or repair an antenna, while a tag team of one person watching the television picture in the living room and another leaning out the window to relay picture quality messages up to the roof while adjustment were being made, was the standard modus operandi.
