Re: These Ducks Quack !!!

 
 
Thanks for the tips, guys. I fashioned my own with poster board, foil, scotch tape and a glue stick. All the math was total Greek to me, so I just eyeballed it. I don't know if I got the "focal point" or not, but what I *do* know is I went from 2 bars to 5 bars (average) on the Windows XP signal strength meter. Very pleased. Now if only I could get these made in Mexico and then sell 'em cheap on eBay!

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

You need to go read the copyright information at the top of the page again... The first person who does that IS going to owe me a whole BUNCH of money.

Oh, and you DID get the focal point wrong.

Thanks

lol.

How about you get a percentage of the quality parabolics that I make?

If not, I will change it slightly and sell freely.

Indeed.

Although.....

If one wanted to make these antennas commercially, I do not think your copyright would hold up to well..

ummm copyright? on an antenna design that Guglielmo Marconi patented in 1897?

Check out the drawings in Marconi's patent on the link below and the replia of the original parabolic receiver antenna that Marconi built..

»www.sparkmuseum.com/BOOK_MARCONI_PATENT.HTM

Couldn't find an online source to link directly to his patent, but my guess is that his 11 pages filed, making 56 claims about the uniqueness of his parabolic design pretty well nailed it..

The direct link you were looking for;

»patft.uspto.gov/netacgi/nph-Pars···N/586193

Only images of the patent are avalible its so old.

As for selling these on ebay there are tons of guys selling antenna bosting garbage there. These arent garbage. But the market for this wouldnt be too large IMHO. The people who dont know any better will buy the flashy pieces of garbage already there. (just like the fools who paid $19.95 for those stupid cell phone stickers that were supposed to boost your signal). The people who know what they are doing will simply follow the plans.

Personally I dont think anyone should be worrying about making a profit on ebay on these things, lets just enjoy using them.

The world is really a small place and those of us who do this kind of stuff tend to be a tight knit community. Often we may not agree on some things, but we remember the folks who not only stuck the umbrella up the wrong place, but then opened it before the pulled it out. People get real upset when you borrow their ideas. Not a good way to get help, and a worse way to make friends.

Agreed.. I think there's more fun and general interest in everyone learning a little more about antennas and getting the opportunity to do some hands on experimenting..

As shown, the materials needed aren't a big deal and if you got a signal strength indicator in your wireless software, and an inquisitive, yearning to learn attitude, you got all you need..

This approach and attitude of learning, passing on knowledge to other interested folks is still a big enjoyment factor in ham radio and a huge part of it's history and reason for being.

And thanks for the link to the patent office.. Lot's of fun to poke around in there on topics of interest...

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

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!

Thank you sir for replying... I get touchy sometimes. In this case I didn't see the joke but I do understand. I might have said the same thing were the shoe on the other foot. You see I made it available to the public against the advice of council. The initial concept was to have a postivie impact upon network security. I hadn't thought of actually selling the thing until it got to be quite popular (3500 downloads last month and 2500 in December).

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.
