You are going to need to find a point near enough to you where you can locate
your gear that will connect you to your cable/dsl acccess point. It
needs to have
a structure high enough to get line of sight to you. You will probably
have to put
in some form of tower on both ends unless you are high enough that from your
roof you can see the target CLEARLY with no obstructions even near the ray path.

Here is a good web site for both equipment and some info determing the ray
path between the two points.

http://www.fab-corp.com/

The are located here in the bay area, but most of what they do is done mail
order.

They build a patch antenna 802.11 radio and amplifier in a singl box for just
such links. There is a path tutorial and also power conversion chart with some
guidance there.

Look at the path tutorial particularly the part about fresnel zone
issues, fading
due to fresnel zone obstruction is the heart ach of many a otherwise good link.

They key is a clear ray path between your two ends. Also if need be 802.11
does provide for digital repeaters so if you do have a obstruction you could
place another support structure on the obstruction and install a
digital repeater
to get the link made. Two of the above devices back to back set up in repeat
mode will do the trick.
