Yagi Antenna with Wifi Range Extender?

Hello, 

I am interested in purchasing a Netgear EX2700 to receive a Wifi signal in my garage and connect it to a desktop computer via ethernet cable. Does this unit have removable antennas? I am interested in hooking a 2.4 Ghz Yagi antenna to it (with amplifier) in order to get a signal from my house, which is around 300 feet away. 

Thank you for your answers.
