Satellite Failure

[potiche]

The reason for loss of TV at my flat has been given as a power surge.
If this is so, what other evidence would there be and can this be confirmed by anyone? There were roof repairs at the time & we wonder if the contractor caused the problem.
The repair bill lists replacement LNB, saying 1 of 4 outputs had a weak signal and a 48way multiswitch, saying some of the outputs were faulty.
There are 10 flats in the building, is the size of multiswitch calculated by number of rooms? Is there another way to install using smaller multiswitches that would be cheaper to replace when partial failure happened?
This has all been referred to as aerial problems, I'd say satellite, are the terms interchangeable?

No expert but if it's a mains power surge then other types of electrical items should have been affected. But if the surge was down the antenna cable then I'm unsure what other evidence there would be.
The switch will surely need an output per flat. Even if you used multiple switches to avoid a reoccurrence of this rare (?) event then I'd suspect the surge might run through each anyway. Terrestrial aerial or satellite aerial, they are all aerials/antennas.
