A mobile phone signal jammer with a metal shell refers to a mobile phone jammer whose body is made of metal material, usually aluminum, used as both a shell and a heat sink. So what are the advantages and disadvantages of this metal shell phone jammer? Let's explore together.

First, let's analyze the advantages of the metal case Mobile phone signal jammer:
1. Simple structure: Aluminum profiles themselves are the most commonly used heat dissipation materials, with excellent heat dissipation performance. Moreover, their heat dissipation teeth can be processed into many shapes, which is also convenient to directly serve as the outer shell of mobile phone signal jammers. They have a certain level of aesthetics and craftsmanship;
2. Excellent texture: After processing, aluminum profiles can have a variety of shapes, and after surface treatment, they have a good hand feel, giving people a more textured first impression,
3. Cost economy: because of the large output and wide application of aluminum profiles, the cost is relatively low, which also greatly reduces the material cost of Mobile phone signal jammers, at least saves the cost of a special shell and the mold used for the shell;
Then let's talk about the drawbacks of metal shell mobile phone shielding devices:
1. Poor safety: Due to the fact that the case is a heat sink, and the mobile phone jammer requires a significant amount of heat dissipation during long-term operation, the temperature of the metal case can quickly rise, and sometimes the surface temperature can even reach 60-70 degrees. Human hands cannot directly touch it, otherwise there is a risk of burns;
2. Product appearance: the antenna of the metal shell Mobile phone signal jammer is external and directly screwed to the antenna link base on the body. Nowadays, there are more and more mobile phone interference devices that need to be shielded. When all 2G, 3G, 4G, 5G, and WIFI signals need to be effectively shielded, a mobile phone interference device needs at least 10-12 frequency bands, which corresponds to the need for 10-12 antennas. When such a number of antennas are twisted onto the device, visually it looks like a hedgehog, and there is no longer much beauty to be seen.
3. Poor anti damage ability: for this type of Mobile phone signal jammer, the antenna is screwed on the body, and the power supply is an external switching power supply, which is easy to be damaged. For example, someone maliciously unplugs or discards the antenna, while others intentionally disconnect or damage the power supply, and so on. This poor vandalism prevention capability will bring high management and maintenance costs to users in the future.
