- I'm under the strong impression that this subject has been beaten to
- death, but I went as far back as I could for previous articles and
- couldn't find a thing. Anyway, I our household does not have cable.
- Instead, there is an antenna set up in the attic that is connected to
- cable wires (don't know for sure) that run throughout the house.
-
- Several appliances seem to introduce EMI/RFI to the TV signal, namely
- my CD players (portable and component), my PC (386DX), and the usual
- hair dryer, maicrowave, etc. I'm interested in finding out what I can
- do to make the TV signal more pure. Here are some observations:
-
- Moving the PC downstairs (away from the attic antenna) helps alleviate
- interference.
-
- Surge protectors featuring EMI/RFI filters didn't improve the quality
- of the TV signal, regardless of where the protector was plugged in,
- namely neither the TV or the PC.
-
- UHF channels are more immune to EMI/RFI than VHF channels.
-
- I'm really not looking forward to the idea of building Faraday cages
- for ALL the appliances and the computer, so any suggestion that is even
- remotely more elegant is appreciated.
