Rooftop access and power

[Christian McArdle]

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.

[The Natural Philosopher]

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..

[John Rumm]

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!....
