Will this work? Advice on the setup.

My dad still hasn't got onto the internet. He comes to our house to use it and is getting there. But still no connection of his own.

He lives quite close, approximately 200 meters - There is a line of sight from my roof to his - Possibly slightly obscured by the tip of some trees (I think its ok though).

My question to you is this:

If I were to create a parabolic antenna using a satellite dish (560mm x 460mm) and connect it to a bridge/repeater at my home. Then create a second identical antenna for use at my fathers connected to a bridge/repeater. Then somehow align them up - Would it work well?

Any advice on this also, I am experienced fitting satellite dishes for digital TV but this is the first project of this type I will undertake.
