802.11b Homebrew Antenna Shootout:
“My plan was to get relative performance measurements for various designs (including mine) of homebrew antennas for 802.11b wireless networks. To do this, I setup a wireless link and changed only the antenna- recording each antennas’ performance under identical conditions.”
The results surprised me! In our test, the Flickenger Pringles can did a little better than my modified Pringles design. Both did no better than the Lucent omnidirectional. Now this is just on raw signal strength, noise rejection due to directivity still makes a directional antenna a better choice for some uses even if there is no gain benefit. The waveguides all soundly trounced the Pringles can designs. I mean they stomped them into the ground on signal strength – as much as 9 dBm better.”
