 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!
