Lost My Wireless Antenna Lost My Routers Antenna... Now What?

Lost my routers antenna... now what? - lost my wireless antenna

Previously, he pulled my antenna wireless router and put it in a safe place to prevent someone from breaking my attmpting WEP. Well, I have a laptop and the antenna is not lost because of the ruthless cleaning.

There is a general-purpose antennas can connect to the router? Hacks or otherwise intelligent (but) not dangerous to increase the range?

thank you very much:).
