First of all, you need to explain to the jammer manufacturer the application site of the jammer you want to purchase and the size of the shielding area. Another important point is whether there is a signal transmission tower built by the operator within a radius of 500 meters. These are all direct Affects the model selection of the jammer. signal jammer
1. Shielded frequency range: Before purchasing, you need to understand what signals you need to shield. General signals (2, 3, 4, 5G) can be shielded instead. If you only shield 2, 3, 4G or only Shield 5G, this can be adjusted before shipment. Current mobile phone signal jammers use full-band shielding. If customers need to block a certain signal, they only need to assemble the corresponding antenna to the device.
2. Applicable sites: Regarding the application site of shielding, if it is used in a room, the shielders generally suitable for examination rooms, conference halls, offices and other areas are of the same type. The gas filling station must use explosion-proof and heat-resistant ones; if If it is a large outdoor area, you need to use a medium-power signal jammer to achieve a suitable distance.
3. Appearance: The appearance of the shield can be divided into external antenna and built-in antenna. Generally speaking, the external antenna is because the antenna is external and flexes outward, so compared with the built-in antenna, it occupies a larger space. A little; at the same time, due to the outwardly expanded antenna, the actual effect of the external antenna is smoother.
4. Power size: Jammers can generally be divided into low power, medium power, and high power, with power ranging from 3W to 100W. When we recommend that consumers choose a Texin mobile phone signal jammer, it will be based on the total area of shielding required. .
5. Shielding range: Shielding range and power are directly proportional. Generally, low-power signal jammers are more commonly used in examination rooms. One is enough to assemble in a classroom, and the shielding range is approximately 100 square meters; while high-power shielding The shielding distance can be 300-400 meters, depending on the local magnetic field strength.
