The objective of this post is to show how an home made WiFi antenna can improve (or not!) the strength of the WiFi signal.
To measure the WiFi signal enhancement of my various “home made antennae” I used the Airport Client Monitor included in the Apple Airport management tools. On the picture bellow you can see my Powerbook positioned 2 and a half meters away from my Airport Express access point. All measurements were made in these conditions.
Four environments were measured:
- Neutral test (the Airport Express itself).
- Chinese kitchenware test.
- Beer keg test.
- Metallic place test.
The measurement reported here are far from following any scientific and reliable method.
The test results confirmed that placing a metallic device behind a WiFi antenna (more or less around the right distance (focal point)) enhances signal strength. The Chinese kitchenware improves the WiFi connection by +10dBm and – unlike the others homemade antennae – gives a stable signal!
