This radio interference countermeasure can block all radio signals of broadband transmitters with frequencies of 870 to 880MHz and 930 to 960MHz from 1805 to 1920MHz, 2010 to 2145MHz, 2400 to 2500MHz, 2300 to 2370MHz and 2555 to 2655MHz. It is used to block the signal between the sending station (base station) between the mobile phone and the wireless device, and the wireless signal can block 2.4. This electromagnetic shield effectively shields the microwave signal between the transmitter (base station) and the mobile phone, so that the outside world and the mobile disconnect contact (GSM, CDMA, DCS, PHS, 3G, 4G, etc.) in the required The masked area may be disturbed. We have portable mobile cell phone jammer and fixed super jammers. The product is easy to use, compact and can be delivered separately, and can be used in a wide range of environments. Fixed jammer advantages: broadband, high power: solution broadband power gain (increase and stable power gain boost control, as well as the smoothness of the waveform band blocking, external band control transmission band index and output broadband index heterogeneity Aaryl and A Repeated R&D procedures for finalization, normal production, product quality and stability in the future), omitting some indicators, it is also an ideal choice for debugging!
Interference between multiple systems: small instruments in the excavator space, CDMA, GSM, DCS/PHS, 3G.4G 6 systems, mobile jammers with high power, broadband, and high resolution while transmitting with multiple signals. Signal, intermodulation will occur between indicators! Long-term, uninterrupted operation: high-quality component equipment, metal, and good heat dissipation performance can work for a long time 7×24 hours without affecting equipment performance. Only the active segment has downlink interference and no mechanical frequency interruption. CDMA output port: 870 to 880MHz GSM output port: 935 to 960MHz DCS / PHS output port: 1805 to 1920MHz 3G output port: 2010 to 2025MHz 3G output port: 2110 to 2145MHz 4G output port: 2300 to 2370MHz 4G output port: 2555 to 2655MHz
One of the main sources of GPS interference is Hongqi 18-1, which is the first stage of the annual air war game. The game is held every year at Nellis Air Force Base in Nevada, and the event extends north to Seattle Air Traffic Control. Electronic warfare aircraft, including the Navy’s Growler EA-18 and the Air Force’s Compass Call EC-130, will shut down all satellite navigation systems within a radius of 450 nautical miles. gps jammer work by generating white noise radio signals whose transmission frequency is the same as that of GPS satellites, which can block signals from GPS tracking devices and navigation systems. GPS jammers are easy to manufacture. GPS signals are relatively weak and centered on the 1.0, 1.2, and 1.5 GHz frequencies in the microwave spectrum. Simply launching microwave energy near the receiver will mask the weak signals sent by the satellite (about 20,000 kilometers apart) and disable the GPS device.
