Another alternative is to mount a USB based card on the aerial. This would be easy enough to waterproof and would need only a single USB cable for power and signal, whilst enabling an extremely short aerial downlead.

Or for that matter a small WAP, and that way you could run cat5 without the length limitations of USB.
And half of those use 'plug in wall warts' whose LOW voltage leads could be simply extended..so no need for main power on the roof at all..
Better still, you stick the power down the unused wires in the cat5 so you only need one cable making the trip outside:

power over ethernet adaptors accept an input form the original wall wart PSU, and combine it with the cat5, then at the remote end break it out again to a short flylead that powers the device.
In fact a lot of kit has the POE function built in, most of the Seano units have, as we have some in use in that very fashion!....
