normally for community installation i would lay all new cable where possible.
i would not touch an exisitng installation unless i was asked to.
if you have lost the spanish channels since the installation of the community dish then i would be certain that the dish installers are using the spanish tv cables.
many "rebroadcaster" installers also did this when installing their systems, use whatever cable it there snip and install. many have found this recently when their rebroadcast systems were turned off and they tried to get their spanish tv system up an running again.
no too sure what you mean by this. if they have had a proper installation then they should be getting over 100 free tv channels from the satellite. unlessThey have had lots of problems with picture quality and I believe they have around 20 channels.
a) it is a rebroadcast system they have installed
b) they have installed a series of receivers at the comms room / head end, with each receiver tuned onto one channel, then those signals sent down the existing cabling (in theory this is also rebroadcasting!) - so each household will not have their own receiver, they just plug in a tv cable into the socket, scan for channels and watch - not a good community system at all.
c) they are just crap installers
a trip with a camera to the comms room where the TV equipment is installed would reveal what they have done
its unlikey the spanishbuilders have done anythings wrong especially if the system was working ok prior to installation.
