To kick it off, i'll post mine.

I'm running a D-Link 900+ hardware access point, this is mounted in a waterproof box from Dick Smith (thanks to help from shadowX), i've stripped off the outer shell of the AP, and mounted the aerial connector (RP-SMA) on the outside of the box, for ease of connecting/disconnecting.

I'll be using a DC cable to provide power to this unit, as PoE would drop ~40% of my power over the distance i need to run as the AP runs at 2A/5V. The cat5/DC cable will be housed inside a flexible conduit to sheild the cables from the elements (as the cat5 cable i'm using was not treated for UV).

The aerial i'll be using is a 9dbi pacific wireless omni, which was purchased from fab-corp. As previous tests have shown, this aerial can reach 5km+ if not obstructed, so it'll be perfect for my uses.

I am yet to mount this on the roof, I need a smaller power connector for my AP, as the one that came with the unit doesn't fit into the box that i have. I'll be picking up an angled power connector this week, and mounting the box this weekend hopefully.
