Comics in modern magazines are a rather rare phenomenon for some reason, but they were fairly regular features up until a couple decades ago. This set of electronics-themed comics is from the December 1949 edition of Radio & Television News magazine. The first one would probably not make sense to someone not familiar with the extents to which some radio operators go to deploy antennas. During field day events and other mobile scenarios, Hams have been using kites and balloons (see More on Balloon-Supported Antennas) to create 1/4-, 1/2-, or even full-wave vertical antennas with wires run along the tether line, a la Benjamin Franklin. When a kite is used, because of the wind carrying the kite away from the ground point, it is impossible to get the antenna vertical unless the line is really long and the antenna wire is located on the most vertical section of the line's catenary shape. The slanted antenna creates a radiation pattern that is directed upward on the windward side and downward on the leeward side. Under low or no wind conditions, a balloon has a better chance of enabling a near-vertical antenna. BTW, I colorized the pictures, so blame the weird combinations on me.

About RF Cafe 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 lady's voice announced "You've Got Mail" when a new message arrived... |
