3-4kms say about say about 2 miles, I am not too sure on this without some kind of repeater.
How much output is your run of the mill card or wireless point got, about 500mw is it not so that's about 1/2 a watt! not a lot of power.
I don't know much about wireless networking, but I know a bit about radio communication and radio wave propagation from using radio communications years ago.
Unfortunately I would say it would be against the FCC laws to use any kind of microwave amplifier to boost that 500mw is it is 500mw for a very good reason, so forget that but you can to what you like when it comes to antenna.
What you do have is directional beam antennas like the yagi, what this antenna does is put all its output in one direction, hence the name beam.
It differs from a omnidirectional antenna as omnidirectional antennas put there power out in all directions, so if your access point is north then a omnidirectional will put its output north south west and east waisting a lot of power in the process.
With directional it will only go north south west or east depending on where you point it. So a directional will always have more power than a omnidirectional, for point to point communications its always good to go directional.
You got to make the most of the 1/2 watt of power, location of antenna and propagation method are most important. I am not a expert on the subject myself.
