According to the tests we made, the antenna bi-quad is sometimes more suitable for use in an internal omni antenna. En effet, l’avantage de cette antenne est qu’elle est directive, mais l’angle d’ouverture est suffisament large pour arroser la surface d’un appartement par exemple. Indeed, the advantage of this antenna is that it is directive, but the opening angle is large enough to irrigate the surface of an apartment for example.
Il existe sur le net plusieurs versions de cette antenne, dont la réalisation est très simple et facile. It exists on the net several versions of this antenna, which is now very simple and easy.

Like many would-be 802.11b hackers, I'm increasingly obsessed with pushing more bits further and faster for less cost (I believe the unofficial goal of our community wireless project is to provide infinite bandwidth everywhere for free. Of course, there are problems with approaching infinity, but it's still fun to try!)
The work that Andrew Clapp and others have done is helping to demystify the ancient black magick of Resonance (i.e. antenna building). And so, over last weekend, some friends and I decided to give it a go for ourselves.
(standard disclaimer): Anything you do with your gear is YOUR RESPONSIBILITY. This is a stupid idea that will probably ruin your radio, set your house on fire, bring the FCC to your door, ruin your crops, and send famine and pestilence across the land. And as the operator, it is YOUR RESPONSIBILITY to not take the word of some raving lunatic on the web with funny colored hair, and find things out for yourself. Your mileage will vary. I'm probably lying. You have been warned.
Anyway, our first run was a direct rip-off of Andrew Clapp's terrific original design (knowing next to nothing about antenna construction, it's helpful to start off with a working known good.) By using PVC, all-thread, washers, some cheap copper tubing, a Pringles can, and some scrap cardboard, we were able to make a prototype shotgun yagi in a matter of hours. Having a couple of other excited alpha geeks around can help move construction projects along very quickly.
