    EV> Howdy! Roy,

    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.   
      
    RW> Did he mention that the mirror of the driven loop is slightly   
    RW> larger than the driven loop?   
      
   I figured 'all by myself' the rear loop would be slightly larger than   
   the driven loop 'cuz reflector(s) are slightly larger than the driven   
   portion of the antennas I've read about.   
   -snip-   
    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?   
      
   I meant that I never heard of any name for those antennas.   
   To me they were just some antenna the CB'ers learned about, as I never   
   saw any mention of them in the literature that I read.   
   -snip-   
    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.   
      
    RW> An 40mtr inverted V with coils to make it electrically longer   
    RW> for 80mtr?   
      
   No, just two 1" O.D. aluminum pipes that was put together to make a   
   Long Vertical Antenna somewhere around 20 foot long, with a 3" Coil at   
   the bottom with a flea clip connected to the center conductor of coax   
   to place on a coil winding for tuning it to a frequency in the 80M Ham   
   Band.   
      
   For 40M the flea clip got put at the top winding of the coil attached   
   to the base of the vertical pipe.   
      
   A wire connected to the shield of the coax went down to my ground rod   
   because my Ham Shack was on the second floor.   
   I never thought of it b4 but what I used looked sorta like a Vertically   
   Polarized Dipole (Electrically) to my rig.      
   -snip-   
    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-   
      
    RW> Not this one. She's about 5'5" and the one she is holding is as   
    RW> wide as she is tall and the perportions of it to the doorway   
    RW> behind her and the pickup truck she's standing next to give you   
    RW> an idea of how big it really is.   
      
   One night someone talked about UHF at a Club Meeting and showed a   
   waveguide to the group.   
      
   It was a 12" long piece of copper sheet bent in a Rectangular Shape,   
   and was about 2" High and 2.5" across and a metal tube was in the   
   center of it and I think some Capacitors and maybe some Resistors.   
   -snip-   
    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?   
      
    RW> I dunno. Do you have scald marks where that coffee got to you?   
      
   Twasn't Me! I thought I saw the News say it was a Woman that took   
   McDonalds to Court, not a Man as I am.
