[QUOTE="PaulR, post: 869237, member: 176256"] They are also known as launch amplifiers and do indeed amplify the signal. As Rolf says they may then go to a multiswitch somewhere but they may also go to splitters to feed multiple multiswitches (one per floor perhaps). As Rolf says it would be far too easy to cause a secondary problem which might take even more time and money to sort out as it might obscure the original fault. Does every resident on the system experience the same problem? Has every channel been lost? The one thing I might quibble about is the comment about the dish being old. Dishes do not necessarily degrade significantly with time. If the 2.4m dish is, for instance, an Andrew/Channelmaster/Raven (different names through the years) or Prodelin then these are made from glass fibre with a metallised reflecting layer under the skin. They will last virtually forever and it's the metal brackets (very substantial normally though) or LNB which will fail first. You need someone with a meter who knows how to use it to trace the signals through the system. Is there not a plan of the system somewhere? A professional would surely have made one when the dish was originally installed. One quick thought. Did you have any strong winds just prior to the problem? A 2.4m dish would need moving only slightly to lose everything - which is why very strong .mountings are needed [/QUOTE]
