Hand held signal shielding device is our factory using advanced technology, for the contiuous developmentof communication standards, according to the actual situation of domestic and international wireless communication to develop a successfu high-tech products; can efctively shield (CDMA/GSM/DCS/2G/3G/4G/WIFI/GPS/GPS/5G/5.8G/VHF/UHF) andother wireless signals, and other electronic devices around the communication and transmission without any negativeimpact and interference. The machine can efectively shieldthe above wireless signal in the range of 5 to 20 meters.
Highly concentrated energy signal antenna jammer
Antenna jammer radiate jamming signals at opponents, blocking receivers with highly concentrated energy signals. The main disadvantage of this technique is that the jammer spreads its power over multiple frequencies, making it relatively weak on a single frequency.
While “interference” generally describes unintentional forms of disruption during wireless communications, “jamming” describes the deliberate interference with or blocking of such communications.
Currently, there are several countermeasures against interference. Similar to jamming techniques, these countermeasures have varying degrees of effectiveness. In addition, specially designed anti-jamming antennas are already available. EW developments continue to evolve as new radio frequency technologies become available.
