Satellite TV receivers, recently ours here are not working, 70 kilometers northwest of Shijiazhuang, do you know why?

No, it's a jammer installed nearby. The installation of jammers is illegal, you can report to the local radio administration complaints, satellite signal jammer transmitter power is powerful, not only on the satellite signal, on the cell phone radio b / / h, in all have interference, and on the personal health hazards, especially children and pregnant women. Before removing the jammer can remove the interference themselves: satellite TV signal jammer precautions 1, looking for shielding location Satellite signals are coming down from the sky, wired interference signals are emitted on the ground, the angle of emission of signals between them is not the same. You can find the interference wave can not interfere or interfere with the location of the small, that is, the interference dead zone. Interference waves and satellite waves are linear waves, traveling on the way to meet the obstacles will be reflected, but the difference between these two waves is that the interference wave field is stronger than the satellite wave tens of millions of times, resulting in the encounter with the obstacles and buildings will be reflected around, while the satellite wave if there is no antenna reflected by the surface of the ground is easy to be absorbed. The easiest way to find the shielding location is to reduce the height of the antenna, because the jammer in the transmission of microwave interference signals have a certain height. Secondly, you can use the surrounding natural objects to avoid the surrounding strong microwave interference signals, such as placed on the open ground than on the top of the floor on the effect is good; you can also move the antenna to the other side of the building, the use of buildings to block the interference wave from the direction of the interference wave. 2, retrofitting anti-jamming devices Judge the source of the interference wave direction, in the antenna on the side of the side or side of the metal mesh shielding the interference wave, will be the interference wave reflected back. The height of the metal mesh should be more than the satellite antenna on the high-frequency head, and can not be blocked to the satellite signal line of travel. As the C-band signal wavelength in 71.4mm ~ 88.2mm between, if the use of metal mesh shielding interference waves, in order to prevent interference wave leakage into the metal mesh, mesh aperture should be less than the shortest wavelength of 71.4mm 1/4. that is, 71.85mm. interference is not too serious, you can also be in the antenna along the outer edge of the plane perpendicular to the pot mouth, plus a circle of width of 10 ~ 20cm of the metal band. Of course, the wider the width of the metal strip anti-interference performance is also the stronger, but a pot of multi-star antenna should not be used in this way, it will block the non-perpendicular to the pot surface of the satellite signal reception
