If you think you have a BIG antenna

[nz3m]

I found this surfing the net. It's a 5 element YAGI antenna for 75-80 meters. Look at the boom, you can see a man walking across it.

I think this would work better than my Windom http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

Looks to me like a horizontal tower rotating on a verticle tower. Holey Moley....The xyl says go for it...I get tired just looking at it.

I wonder if he would adopt me as his son?

That is a piece!

Also just impressed by the rotor shaft.

A local (to me) amateur has had a full sized 80/75 meter 3 element yagi up for years. The boom is made from Rohn 45 tower. The elements are "tunable" from the ground so that the entire band can be covered with maximum performance and minimum reflected power.

Does it say "Made by Boeing"? Holy poop....

That thing is big. A neighbor of mine has a pretty large antenna also.Click Here (http://unitedtamers.freeyellow.com/DCP_0004.jpg).

I always slow down and admire it when I pass by his house.

Maybe he can contact Beagle2!!! #Cripes, certainly he wouldn't miss my &quot;stealth house&quot; i'm building at the base of that monster.

Your neighbour has a pretty small tractor!

I doubt all these hams are married.
Some housewives would dream of it... to hang the clothes http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif

I think the guy missed the old saying &quot; If it doesn't come down in the winter, it is not big enuff&quot;. http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

Elsewhere on the guy's web site he says:

&quot;P.S. I'd like to answer as many questions as possible. However, I request you not to visit or call me. I've got jobs to do and have a family. Please contact me by &quot;mail to the owner&quot; on the top page.&quot;

I reckon he must have got fed up with passing hams - 'Oh go on, let me have a quick go'.

WZB: Does he actually feed that thing? What does it eat?

Where is the pix when raised up 100 feet?

Not Bad, but you want BIG?? Check out the High Frequency Active Auroral Research Program, or HAARP for short, at http://www.haarp.alaska.edu/ Now that is BIG! For anyone who might be interested, there is a nice write up in the January issue of CQ magazine on HAARP written by WB6NOA, check it out if you get the chance, very interesting indeed.

That second array that KD5WZB links to was featured in QST some years ago. I remember he turned the whole thing with a pickup truck at the end of it that rode around a track. That's a moonbounce array for those who may not know.

I recall vaguely that Glen knows the guy.

And to think, in 29 years, the biggest antenna I ever had that wasn't only wire was a seven element 2m antenna in the attic when I was a teenager.

Wow, that's an impressive array also. It was built for research.

This guy is just a ham who wanted a big signal on 75. If you look on his site, there is a picture of his QSL, where you can see his other towers.

Yeah, it is for EME, and you can see the vehicle used to turn it on the left side support... you can see a bit of the track under it's tires also. I havn't talked to him in person, but I have e-mailed him, and he is a real nice guy. I beleive he calls it the &quot;Mighty Big Array&quot;.

Glen,

Get us a picture of that monster! http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif

[K9STH]

I haven't been out to K5GW's &quot;antenna farm&quot; for quite a while so I'm not sure if it is one of his &quot;moon bounce&quot; arrays that has the truck. He is the one with the 3 element 80/75 meter yagi with the Rohn 45 for the boom.

Gerald is probably better known to the amateur radio &quot;masses&quot; as the owner of Texas Towers. By the way, Gerald's photo is on page 84 of the January 2004 issue of QST and Ed Hare (regular poster on this site) has his photo on page 12 of the same issue.

There was a fellow back in the late 1950s who had a rotatable rhombic that floated on his farm pond. It used a tractor on railroad tracks for the rotator. However, being &quot;bi-directional&quot;, he had only to rotate the rhombic through 180 degrees instead of 360 degrees!

Glen, K9STH

[K7KBN]

KC8QMU - that array serves as a rotatable dipole for 160! Check out the owner's comments.

And for those who are interested in rhombics and haven't seen the W6AM antenna farm: W6AM (http://home.swipnet.se/dx/porthole/w6am1.htm)
