Not sure how it's distributed after the units you show, but I would guess through a series of taps or a bank of splitters.
The second picture shows the channelised terrestrial amplifiers which are fairly straightforward, but not sure of the satellite/IF system, have never used anything like that, it appears to be a SMATV system, distributing a few satellite channels as UHF channels. These would pass along normal infrastructure coax.
We have a few system installers here who will know more about it and I'm sure pass comment on what a crappy installation it is as well.
