It Would Make A Swell Fan, Too (Feb, 1940)

It Would Make A Swell Fan, Too

IT LOOKS like a new-fangled kind of windmill, or at least a trick water turbine—but don’t let appearances fool you. It’s an unusual aerial designed for W6XAO, the only television transmitting station in Los Angeles. The aerial is 60 feet high, and the paddle-like elements are intended to produce television pictures with better definition than former aerials have given. Made of duraluminum, it is being inspected by Harry Lubcke, its designer, and Thomas Lee, who owns the station.

    So that’s what we had on the way to developing High Definition; “Better Definition” which supplanted “Good Definition” that came after “No Definition” or radio.

    Windmills do not work that way!!!

    I’d really like to know, what’s the theory why those paddle shaped elements would be better when compared to normal ones.

    The word “fan” might actually be significant here, Jari. There is a type of antenna called fan dipole, better known as “bowtie”: (http://www.hdtvprimer.c…)

    The latest in HDTV antennas is this type: http://www.tvantennapla…

    There is a picture of the installed W6AXO antenna here: http://www.earlytelevis…

    Thanks Randy. But now that I saw the pic of the erected antenna, I’m even more puzzled, as the “paddleside” of the elements seem to be vertical…. Unless the idea is to make transmission beam wider, than from normal dipole. Let’s see, if I can find my old army notes about antenna theory and signal propagation.

    You’re at least one up on me then, Jari. The only antennas I’ve ever built were straight Yagis. And any connection between a fan dipole and the Lubcke antenna is probably tenous at best. I did have some interesting reading about Mr. Lubcke though. He had been an assistant of Philo Farnsworth, an early president of the Academy of Television Arts and Sciences, and named the Emmy Award (though he originally called it Immy…)

    Heh, I haven’t done much else than Yagis and a handful of logarithmics myself, but that’s years ago. Btw. I’m a DX’er, not a Ham. Unfortunately building codes prevents raising a mast, where I live now…. So I’ll just have a go with a not-so-longwire from time to time. I’ll need to dig out more of Mr. Lubcke, when I have time.

    I have fond memories of BCB DX’ing as a kid in Nebraska in the 1970’s, with just a little pocket transistor radio using its internal ferrite antenna. I had over 150 stations with it, the farthest being HCJB down in Ecuador on (if I remember) 800kHz, but it was a real powerhouse. There was another station on the frequency in Mexico, so I had to turn the radio just so to try to null out one or the other.

    I got “bitten” by half-70’s, when my parents bought a DUX stereo center (licensed Philips made in Sweden), which had a good tuner with SW, MW and LW. During night time, sitting next to it wearing headphones. Trying to figure out, what is that weak station, that’s partially submerged by some really loud Russian station. 🙂
