[3] At 2.4 GHz, losses can occur if the cable from the cantenna to the Wi-Fi circuitry is too long.
[4] Cantennas are typically used for extending a wireless local area network (WLAN).
Cantennas can be used to increase cell phone range,[5] improve reception, and decrease noise.
The 5.5 GHz cantenna dimensions are almost perfect in that they make a good fit for the standard TV satellite dish.
[6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links.
