   Antennas by Roy

   Greetings Ed!   
      
    EV> 05-15-14 11:56 Roy Witt wrote to Ed Vance about Antennas by Roy   
      
    RW>> @MSGID: <53753B3A.438.amtradio@capcity2.synchro.net>   
    RW>> Greetings Ed!   
      
    EV> Howdy! Roy,   
    EV> -snip-   
      
    EV>> So a Quagi looks like it has two square reflector sections instead   
    EV>> of reflector elements?   
      
    RW>> No, a Quagi has a quad reflector and driven element. The rest   
    RW>> are parasitic orhestra* leaders. 8^) > directors*   
      
    EV> Yes, Tom already set me right about Your antenna.   
      
   Did he mention that the mirror of the driven loop is slightly larger than   
   the driven loop?   
      
    EV>> As I was typing near the end of this message I remembered a SQUALO   
    EV>> Antenna, if I spelled it right, and just had to write about it.   
    EV>> I think it was a Square Halo antenna way back in the 1960's for 6M   
    EV>> and maybe 2M. It's been a L O N G time since I've thought about   
    EV>> those.   
      
    RW>> SQUALO is an acronym for Square Halo antenna. These aren't the   
    RW>> same antennas.   
      
    EV> That's as close as I could tell from the antennas I've seen   
    EV> advertised in the Ham Radio Mags long ago. -snip-   
      
   I can't quote it verbatim, but the Quagi antenna written about in 73   
   Magazine wouldn't have called it a Squalo or anything but what it   
   really is, a Quad antenna with 5 or 6 orchestra leaders.   
      
    EV>> It has been a long time since I seen a Gizmotchee Antenna.   
    EV>> The ones I saw IIRC only had two sections, Yours has four.   
      
    RW>> Note that it has one driven element for either vertical or   
    RW>> horizontal polarization. Tha required two lengths of coax run   
    RW>> to a switch box at the operating station. I used RG8 for that.   
    RW>> Coax was cheap in c1969.   
      
    EV>> Remember I never heard them called by that name until You mentioned   
    EV>> it some time ago.   
      
    RW>> What were they called then?   
      
    EV> I've got no idea what they were called, I just thought they were only   
    EV> on houses where someone used a 27 Mc/s Citizens Band Radio, I never   
    EV> saw one in any QST or CQ or 73 Mag advertisement to know their name,   
    EV> or who manufactured them. Back then Mosley and Hi-Gain were the   
    EV> companies advertising, Beams and later I remember seeing Cush-Craft   
    EV> antennas advertised.   
      
   I once saw a box that a Gizmotchee came in. A friend of mine in Illinois   
   had one mounted on his barn way back then.   
      
    EV> I forget who it was that made the V-80 Vertical that a friend sold me   
    EV> to use on 80M and 40M, I only now remembered it was called the V-80.   
    EV> That was my first Antenna and it was a long time ago too.   
      
   An 40mtr inverted V with coils to make it electrically longer for 80mtr?   
      
    EV> Later on I got a Hustler Center Loaded Whip, but I don't think they   
    EV> made any Beams.   
    EV> -snip-   
      
   While rummaging through some junk last week that I aquired from a woman   
   whose husband had played with CB before he croaked, I found a mobile CB   
   antenna with a base loaded whip. Then yesterday, while visiting a body   
   shop who had repaired my pickup, one of his employees had an identical   
   antenna mounted to a steel post and he was using it for his FM-stereo   
   reception antenna inside of a tin building. I then realized that most   
   truckers use the same antenna for their OTR communications and they're   
   available at any truck stop.   
      
    RW>> I also have one of my wife holding a wave guide in front of the   
    RW>> back door to my shop; to show it in proportion to familar   
    RW>> things.   
      
    EV> I've seen them too, they're real small, but they do the job.   
    EV> -snip-   
      
   Not this one. She's about 5'5" and the one she is holding is as wide as   
   she is tall and the perportions of it to the doorway behind her and the   
   pickup truck she's standing next to give you an idea of how big it really   
   is.   
      
    RW>> IMO, Wayne Green did that the best of all. Yeah, he rambled on   
    RW>> about his US Navy experiences during WW2 aboard a submarine,   
    RW>> but he also had some very interesting and challenging ideas.   
      
    EV> Never Say Die is what came to my memory when I saw Wayne Greens name.   
    EV> -snip-   
      
   That was his motto...   
      
    EV>> There are thoughts I remember sometimes of things I experienced many   
    EV>> many years ago and probably are of no use to most people, but once   
    EV>> in a while those memories come back to me and I even may mention   
    EV>> them to someone.   
      
    RW>> That's ok to do, as it is something you have experienced   
    RW>> yourself. Quoting someone else's work to bolster your position   
    RW>> on something without giving them credit, isn't. And we can all   
    RW>> learn from such sources, if they're given credit where credit   
    RW>> is due.   
      
    EV> When I wrote "experienced" I also meant "remembering what I've read".   
    EV> I don't usually remember who wrote what to give them the credit when   
    EV> I write about what I remember they wrote.   
      
    EV> Such as, I have no idea who wrote this, or if it was a Cartoon:   
      
    EV> "The only time I use the word Hertz is when I stick my finger in an   
    EV> electrical outlet, then I get 60 Hurts per second.".   
      
    EV> I don't know who, but I remember what I saw written.   
      
    EV> But now a days, if someone doesn't like the color of my socks, they   
    EV> can sue me in court and win judgement against me.   
    EV> It worked at McDonalds over Hot Coffee didn't it?   
      
   I dunno. Do you have scald marks where that coffee got to you?   
      
    EV>> While writing the above paragraph I remembered a man I knew in   
    EV>> Alameda, California who was a Ham in his younger days, who told me   
    EV>> he welded two Dimes on his Telegraph Key to use with his Spark   
    EV>> Transmitter, because he kept burning out the contact on the Keys he   
    EV>> used. When he told me this he wasn't licensed anymore but told me   
    EV>> about it after learning I was a Ham.   
      
    RW>> I can believe that. Especially when you consider that sending   
    RW>> morse code requires interupting the Continous Wave of a CW   
    RW>> transmitter. Especially a spark transmitter.   
      
    EV> Of course when He transmitted he didn't have to worry about causing   
    EV> TVI because there weren't any Television Sets. -snip-   
      
   Nope, just RFI...because there were plenty of radios around back then and   
   most of them were barely able to receive a signal from any station further   
   than 20 miles away.   
      
    RW>> Yeup...(as I contemplate the way in which I'll be making that   
    RW>> little UHF LPDA for experimenting on 'how to gain reception of   
    RW>> some Austin, TX HDTV stations' that have escaped me so far)   
      
    EV> I wish You luck in designing and cutting that antenna.   
      
   Oh, it's been designed for a while, I just need to get out of the house   
   and into the shop to begin cutting it...   
      
      
       Have a day!
