USB WiFi dongle and TV antenna “hack”.

The last week or so, I am packing everything in order to move to a new house. During the closet cleanup I found a box containing a cheap indoors TV antenna.

Before the modification I made some measurements for a specific WiFi access point with the TP-Link dongle. The mean value of signal strength (iwlist wlan1 scan) was -68.1 dBm. After the modification the mean signal strength was -54.48 dBm. 13.62 dBm improvement. Not bad.
