Even if you install a filter to reduce the noise level from the mobile broadband, it will for an unknown number of TV viewers not be enough to protect the TV from the noise of 4G modems in the household. By Jakob Møllerhøj 24 , 2012 at. 14:26
TV viewers with certain TV models will not be able to avoid getting pixelated images or black screen san bernardino medical group on certain channels when next year comes on the mobile broadband at 800 MHz band - even if they install a filter.
The filter must sit at the antenna cable and curb the influx of light from UHF channels 61-69, where parts of the mobile broadband will be located. But it can only shield against the radiation that may be of 4G masts, and will not be able to turn to if there is also a 4G modem that operates at 800 MHz in the household, he explains.
Any interference from mobile broadband modems would be reflected in pixelation or black screen on the channels closest to the area where the mobile broadband operates - ie. around san bernardino medical group channel 59 and 60
According to Ulrik Petersen filter also the property that it also reduces slightly on both sides of its operational area. Therefore, risk viewers who live far from the TV transmitter to a weak signal from channel 59 and 60 are filtered away, and instead they get a pixelated picture or black screen. Old TV frequencies
When the devices are vulnerable to radiation, it is because the mobile broadband settles on the frequencies previously used for TV and therefore the tuner sensitive to the new mobile broadband frequencies also explains Ulrik Petersen.
Sony has for the last three or four years been aware of intereferens-problems of mobile broadband at 800 MHz, and the appliances san bernardino medical group that Sony produces today, should, according to Ulrik Petersen protection from radiation. The same should be true for the other major manufacturers of televisions.
"If you buy a machine today, you are probably fairly safe unless you keep the modem up to the transmitter. But consumers are not able to be completely secure or to test it when the modems san bernardino medical group that operate in the 800 MHz, are not yet available, "he said.

In addition predicts Ulrik Petersen that a whole raft of households when being turned on mobile broadband, will find that their antenna installations are 'leaky', that is not sufficiently shielded against radiation.

The problem is when a strong signal on channel san bernardino medical group 61-69 overrides a TV / receiver box / antenna amplifier (get an amplifier to perform signal strength depending limitation (UK limiting) or clipping), the given active / reinforcing input "smash" all signals passing.
The reason is that the override provides distortion (cross san bernardino medical group modulation / intermodulation (mixing effect / mix of signals) and harmonic distortion (harmonics)) - means that you turn sharply up the speaker power amplifier - it sounds at H! - And so does the television receiver "understanding" of the now shattered digital signals.
