Set Top Box problems

[Navrig]

We have a slight problem which I thought was down to the signla from the loft however I think I can narrow it down a bit but still could do with some help.

Occassionaly our STB would drop the signal and we would get black screen for a second or two. This would happen several times per hour on an intermittent basis.

Tonight I managed to get our home office set up including our paper shredder. I tried it out and hey presto the same problem occurs every time I shred a sheet of paper.

Any suggestions?

Improve your signal by getting an outside aerial...loft aerials are prone to interference pickup and the signal is attenuated by the roof/building materials.

Sorry I described our aerial setup wrong.
We have a Sky dish and an external aerial both of which feed into an amplifier distributor box in the loft.

Make sure the paper shredder motor is suppressed.
Make sure your aerial cables are all fully screened.
