Re: Crud generators.
Running CAT5 in older buildings is not impossible and can be done if you must. It may take drilling a few holes in a wall or two, but that is easy even in concrete walls. An electrician will do this easily, and the installation will look professional. Besides, CAT5 outperforms PLT so you will have a much faster network. Introduction of noisy RFI generators like PLT is not justified because of the terrible radio interference they create to nearby radio users/listeners. But of course, it is easy to dump the shit on someone innocent like your neighbour who might be a radio user, and then ignore the problem. A very decent way to behave......
Plasma-TV may have a better picture (regarding black levels, which is very black), but in the last few years the OLED or LED TV's have excellent picture quality, so now they outperforms Plasma-TV's. Take a look at the new Samsung 46" ES8005 LED series which is excellent. And they have no RFI problems and uses only 82w (very power efficient). Plasma-TV's uses twice that or more.
Plasma-TV's have huge problems with RFI, especially in the LW-MW and low HF frequency range.
Most of them does not comply with the essential requirements of the EMC directive 2004/108/EC.
Since there are no EMC-standard for RFI emitted directly from the Plasma screen below 30 MHz, the TV industry have ignored the problem, sending these RFI generators onto the market. Below 30 MHz there is only conducted emissions from the primary side of the TV power cable (AC mains), which is limited by EN55013 I believe. But in a test of RFI directly from the Plasma screen, most (if not all) plasma-TV's have strong RFI, even at 100 or 200 feet away from the TV. The videos abowe demonstrates a 47" Samsung plasma at 200 feet (60-70 meters) away from my wire antennas.
