- ElvisNixon, on 10/12/2007, -0/+2what's the point of 1/4 wave external antenna, since space is an issue, you could make it 5/8 wave by using a coil to make it an electrical 5/8 wave with a quarter-wave footprint.
- pancho, on 10/12/2007, -0/+2This story is *****!!!!
Did you read the story man. He does not make the antenna from a ballpoint pen. He merely states the it could be "it could be housed inside the tube of an old pen"....
The pen is only the housing and does not contribute to the antenna. - emanuelez, on 10/12/2007, -0/+1well the wok really worked perfectly to me... i had almost a 12 dB gain... but yes... it is a BIG wok LOL :)
- Kash04, on 10/12/2007, -0/+1vertigoblue, it works becuase its 1/4th the cycle of a 2.4 ghz signal

- keenanj, on 10/12/2007, -0/+1he is better off getting the best 200mW wireless card it will give hime 9x the range of a standard card.

- ripcrd, on 10/12/2007, -0/+1Don't waste your time with this. All the wireless mods I've seen that were promising involved less work and were backed up by frequency and power calculations. Those guys were electronic and radio techs or electrical engineers with facts to backup why their mod worked. Witness the Yagi Pringle's cantenna.
- oneofmanysteves, on 10/12/2007, -0/+1Pretty cool omni-directional antenna.
- zelig, on 10/12/2007, -0/+1There are quite a few ways to make an omni antenna like this- as long as it's a 1/2 wave or 5/8's wave at 2.4 GHz. This is more work than it has to be.
- thenativeraver, on 10/12/2007, -0/+1I'd rather use a wok and a wireless dongle
- kg4ydw, on 10/12/2007, -0/+0This is an antenna model called a 'colinear'. It is a high gain omni-directional antenna. You can add as many segments to this as you want; the more segments, the higher the gain. Nearly all stick shaped antennas that are longer than 5/8 of a wavelength are colinear antennas.
A normal 1/4 wave or 5/8 wave antenna has a radiation pattern that is shaped like a toroid, like a donut. This antenna works by flattening the pattern into a flat disk with more concentrated power.
This antenna will have less gain than a directoinal antenna like a yagi or cantenna (a cantenna is a waveguide / horn) unless it is much larger, but you won't have to aim it as long as your access point isn't above you (where it will miss the flattened disk). - tomaburque, on 10/12/2007, -0/+0Bad idea even if it works. You know what happens when you mismatch impedence in RF? At best you lose efficiency. At worst you burn out the transmitter.
- Xoligy, on 10/12/2007, -0/+0Brainiac done a similar experiment and layoing tin foil everywhere was nearly as effective as an external antenna, plus it's easier.
- Anchoret, on 10/12/2007, -0/+0Jive article. Saw it long ago and dismissed it:
Attach it to an N-connector?!?! Has this guy ever _seen_ an N-connector?
No gain testing here at all, so failure is presumptive. With the many serviceable wireless analysis programs out there, there is no excuse for not having a screenshot comparing before and after dBi measurements. - vertigoblue, on 10/12/2007, -0/+0why does this work?
- deernick, on 10/12/2007, -0/+0this is cool idea
- Anchoret, on 10/12/2007, -0/+0The "Yagi Pringles antenna" isn't a Yagi. Strange misnomer!
- Braingoo, on 10/12/2007, -0/+0Digg is getting funny if your article is actualy about Tech it gets busted on for its obvious inadiquacy to some other method. I know this method for creating a wireless antenna may not be the best or may not even work but i did find the theory behind the actual creation of such a device very interesting. I posted for technical enjoyment not heated technical debate.
- thenativeraver, on 10/12/2007, -1/+1That can't have much gain.
- Bigopinion, on 10/12/2007, -0/+0There's no debate? I see a debate on whether or not "using a pen" is a possible/practical method. Seems the general consensus is that not only is the title misleading in general, the actual method isn't worth the effort. Yes, we're all aware that some metal objects enhance an antenna signal - people have been rabbit-earing their recievers with coathangers for years.
Finding technical enjoyment in an article usually requires that the article's focus is genuine and worthwhile. Why do I want to bother with a *slight* gain by bothering with a perfectly good pen! - dimatt, on 10/12/2007, -0/+0attempting now....
- GrendelT, on 10/12/2007, -0/+0Read up on antenna design theory. This antenna design has worked on other bands as well.
*I want to retract my digg since the poster obviously didn't read the article. - dimatt, on 10/12/2007, -1/+0It doesnt work, this blows
