Those are pretty clever too. I don't think I've seen one in practice (although I may have inadvertently made one with bad SMA grounding efforts :-))
I picked up a vector signal generator which has as one of its standard waveforms 802.11 (b/g/n variants) I use its output on a bit of coax to the SDR sitting on my bench while working on the WiFi tranceiver code. I have referred to that wireless over coax (it does bluetooth, zigbee etc so those work over coax too :-)).
Back in Blekko's first building space the office was on the other side of the building from the nearest cell tower so we installed one of those cell "repeaters" which was essentially an antenna in the suite connected via a bidirectional amplifier to an antenna on the roof that was pointed at the cell tower. The FCC later outlawed them but I always wish that I had kept it for those situations where cell service was hard to get.
It suffered from the fact that the antenna was not omni-directional so you really wanted it on one side of the space so that everyone in the space would be able to hit it with their phone. It was an improvement though over the AT&T wifi connected "mini cell" because it carried everyone's signal, not just the AT&T ones.

One of these leaky cables would have been ideal.
