Yagi Cantenna (Yagi in a Can) 2.4GHz
Yagi antenna for the 2.4GHz spectrum (Wi-Fi). What’s different about this antenna is that it is inside a cantenna giving it more range by narrowing its beamwidth making it more directional than a standard Yagi.

The cantenna is made from a toilet brush holder. These seem to be a standard size but the dimensions are: 265mm length, 90mm diameter.
To test my antennas I use a test router 40 meters away with the signal going through three brick walls.
