Is it my imagination, but it seems that the guys (across the pond) really have a propensity for sticking things on tops of poles don't they? You can see this in many movies which show (outside) shots of urban areas - Looks like a right monkey's lunch.
Mind you (funnily enough), the installation looks very similar to the old Redifusion link that was installed in many homes (within the UK) during the early seventies.
This was (also) a cable network, mounted above the ground (on poles and between properties), but (unlike today's systems) didn't use set top boxes, instead used a rotary selector switch mounted on the wall, along with a socket for the TV's aerial cable to attach. Ground breaking technology (then), with a selection of three TV and four (BBC) radio channels - whoopee!
Things have moved on a little since then.
