Erskin and everyone else.

As you can see from the pics, I get a marginally better signal with the ducks installed. I don't understand any of the formulas or anything, I just traced the arc and punched a hole at the focal point.

Usually, I am sitting within 30ft or so of my AP, so these things weren't an absolute necessity, I just thought they'd be cool to build. And so easy, too. The hardest part was eating all the Cheez Curls first *burp*

Oh, one more thing... I have my WAP-11 up to 0x90 on the power setting for every channel (I read somewhere it was better than 0x80 I think), but if I put the reflector on (new) 5dBi rubber ducks should I reduce the power to maximize range?

The designer of the antenna talks about the importance of the reflector being a square. The ez-12 template is a rectangle--unless I missed something else.

I believe it is just a case of two different designs. There is no magic requirement for the square dimensions of the first design; it is just that the published calculations assume those values.

Thanks for the link to the ez-12. Somehow I missed that. I think I'll try it first.

A couple of questions though:

And, what kind of glue works to attach foil to card stock? Elmers or something like that?

Got a four pack of Pringles at the local BJs Warehouse with a dollar off coupon.

IMHO the key design issue is getting the cardboard or whatever is used to hold the parabolic reflector's shape and through which the dipole goes through. I've looked at all the pictures and am wondering if a thick piece of styrofoam could do this job. Anybody have any tips on this issue? Thanks in advance.

Am trying to avoid shooting up wires to the second and third floor of my house and/or not having to buy additional access points. Netgear is having a 50 dollar off rebate deal on their APs that expires 3-31, so I'm going to have build this and try it out before then.]]> http://www.dslreports.com/forum/Re-These-Ducks-Quack-6377501 Mon, 24 Mar 2003 22:51:59 EDT Re: These Ducks Quack !!! http://www.dslreports.com/forum/Re-These-Ducks-Quack-6375992 said by netwire:

I just wish the implementation were up to the quality of the pix. My line of sight between the two (single-antenna) DWL-900AP+'s passes through one floor, one hallway wall, and two room walls at a 3D oblique angle (maybe about 5'x6'x15'). Resulting data rates:

1. with reflector - 2.02 Mb/s (megabit per second)
2. without reflector - 2.13 Mb/s
3. reflector backwards - 2.06 Mb/s
4. removed antenna - 1.74 Mb/s

Evidently, the situation has so much multipath, I'd be better off just walking around with a field strength meter to find a good site. (I guess this is what they mean by "hot-spot"!)

At one point I removed the antenna and covered the DWL with the dog's stainless steel waterdish. The whole thing was sitting on top of my steel-case computer with just path to air under both sides of the dish. I was still able to stream audio!

IIRC, the DWL actually does have a second internal antenna for diversity. It may have been ignoring my beautiful parabola at some points in the experiment.

A gentleman named John Desmond mailed it to me. I'll put it on the site next week. He and I have been emailing each other for a few days. I don't know much about him, but he clearly understands optics and photography. He got it by putting a "slave flash down the hall behind a cardboard with a couple of slits in it."

It was so interesting, I've been in the garage all evening with a couple of laser pointers and some templates. It looks like all the templates pass muster -- BUT -- it is a whole lot harder to make a *REALLY* good one than I thought.

I'll be looking at simplification, with an eye towards improved accuracy in implementation because that focal point is *REALLY* important and it is too easy to miss it by a quarter of an inch.

The one at David's site is just a really nice implementation of the design. His numbers show about two dB more than your classic "cantenna" but then he built an 8 inch reflector.

I can't figure out how to add the neon lights but I *AM* working on it.

I've had some trouble with it when I put a reflector together inside the house (68 degrees) and then take the reflector into the garage (30 degrees). The metal wants to shrink and causes the (admittedly very light cardboard) to bend out of shape, but it works just fine indoors. Wifey has a WET-11 template on her computer in the other end of the house thats been there for six weeks with no problems.

You could use foil, metal screen, hardware cloth (that's the 1/4-inch mesh), or even a dissected Pringles can.

Onward to better things. You have motivated me to
design a reflector based upon a corner design.

Excellent! While the parabolic is a cool design, as an apartment dweller without a workshop, it's not too easy for me to build an accurate curve.

What will be cool about the corner reflector is that it's damn simple to build with not much more than tin snips. :)

I'm still searching for the half power beam width equation.

Interesting to note from the pdf of Prof Georgieva's class notes that the first reflector system was made by Hertz in 1888 (cylindrical reflector fed by a dipole). Sounds like the antenna design in this thread.

I used an cheap aluminum cookie sheet from safeway for my reflector. Would I gain anything from getting something thicker?

No, I don't think so. The "skin effect" of microwave radiation keeps the radio waves at the surface of the metal. I remember in my college microwaves class we made a waveguide using the metal coated wrapper from a stick of Juicy Fruit gum!

I couldn't find my old electromagnetics or microwaves textbooks so a quick Googling turned this up:

The microwave currents flow in a thin surface layer of thickness about a "skin depth" from the surface. This is because electric fields cannot penetrate perfect conductors, and only penetrate real lossy conductors a little way. See the text by Kraus on Electromagnetics for a treatment if you like.

I've got a question about the "Diversity" antenna configuration on my Linksys WAP11. I currently have each of my antennas pointed at different areas. One points to the left of the unit on the same floor and the other one points straight down to the floor below. I just can't position my Access Point in the optimum position and sell it to my wife, so I'm pretty stuck with where it is now.

My question is, am I going to have a problem once I buy another PC Card and have 2 laptops going at the same time but each of them operating in the separate areas?

I've read that the Access Point will switch between antennas for the best performing one. But, how often does it switch between the two? Anybody know?

I don't yet have 2 PC Cards to test this out but will be getting another one very soon. Thanks!

Browse to your WAP's IP address and try for the weca.htm or maybe it is html page.

Select use best antenna. It will sense where it hears the client best and use that antenna to talk to that client. I don't know how fast it switches, fast enough I reckon. ;)

Now if you are trying to cover one area, not splitting up the antenna work like you are doing, it's best to stick with the factory defaults, which I believe is diversity.

I am sure there are others here who know more about that than I do.

Nice work. Yes the dipole reflector is the best one for your setup. Reading your graph, it looks like the extra care with the first antenna netted you about 2 dB of gain.

That's nearly twice as good. 8 dB of gain is half as much gain as 11 dB of gain. I say the little antenna is a dipole most surely.

Take that same reflector and put it on a WET-11 and it will perform badly, take that WET-11 template you build and it will perform about as good as the other does with a dipole, you are getting about 10 or 12 dB of gain with the first antenna. Nothing to sneeze at and the workmanship is good.

Nice work.

On a side note, i noticed that my laptop wireless card had a firmware update that I had not applied. That also made a world of difference to the link quality. Did not change the signal though. So if you have a USR pcimca card, you might want to see if there is newer firmware.

If that antenna is about 15cm (~6") long use the WET-11 template. If it is about 9cm (~4") long use the dipole template. In either case try to center the dipole on the reflector vertically and I think you'll get a bit better results. Also a really nice smooth curve with very few irregularities will work better. These reflectors are very sensitive to:

1) Focal point. This is the HARDEST part to get just right.
2) Correct curveature. This part isn't that hard to get.
3) Vertical centering.

The focal point on this template is essentially a pencil sized cylinder and not really a "point". Since the dipole makes a doughnut shaped pattern the idea is to try to get the pattern to center on the reflector from just the right distance.

Nice work, with that unit, you have an opportunity to make an even bigger reflector. It's just perfect to be able to stand it up that way.

I'm pleased that the design worked for you. Thirty to forty feet is pretty close to be able to notice much difference. I've got two units that are about that distance apart but there is a stone wall between them and all I do is go from an 84 percent signal to a 100 percent signal.

Try the same expirement at a mile and you'll notice the difference, in a big way.

THAT WOULD BE A VERY BAD IDEA... VERY BAD.

Sheesh! Sorry, I was only trying to be funny! Guess I better not quit my day job, eh?

Oh, and you DID get the focal point wrong.

You're right, I did. I made these at 2 am when I found this thread. A few days later I actually printed out the template to scale and reshaped the middle part that the antenna plugs into.

Frankly I don't see an improvement in signal strength over the original ones I scratched out by hand. Then again, I'm only operating about 30 to 40 feet away from the Access Point. Perhaps if I was further away the difference would be measurable.

Regardless, I'm a happy camper. Anytime I can tinker and not blow myself up--much less get favorable results--I end up enjoying myself.

Again, thanks for the tips!]]> http://www.dslreports.com/forum/Re-These-Ducks-Quack-5881574 Tue, 04 Feb 2003 13:40:29 EDT Re: These Ducks Quack !!! http://www.dslreports.com/forum/Re-These-Ducks-Quack-5860622
I am just defending the fact that it is possible if one wanted to.

I agree with the two previous posts above me. :)]]> http://www.dslreports.com/forum/Re-These-Ducks-Quack-5860622 Sun, 02 Feb 2003 11:58:32 EDT
