With the continuous development of science and technology, mobile networks have undergone several updates, from the original 2G mobile network to the current 3G, 4G, and even 5G mobile signal networks. Alongside these advancements, the design and functionality of Signal Blockers have also evolved. In particular, the choice between built-in and external antennas has become a topic of interest. This article aims to explore the advantages of Signal Blockers with built-in antennas over those with external antennas.
One of the primary reasons why Signal Blockers used in examination halls and other sensitive areas opt for built-in antennas is their superior aesthetics. The built-in antennas are seamlessly integrated into the device, resulting in a more streamlined and visually appealing appearance. This is especially important in environments where the presence of a jammer needs to be discreet.

Another significant advantage of Signal Blockers with built-in antennas is the enhanced safety they offer. When external antenna jammers are operated for extended periods, the interference device tends to generate relatively high temperatures due to the interference process. This poses a safety risk, especially if the jammer is enclosed in a metal casing. However, the use of high-plastic materials in the construction of built-in antenna jammers effectively addresses this concern. The materials used are heat-resistant and minimize the risk of overheating, ensuring the safety of both the device and its surroundings.
Built-in antennas also boast higher environmental friendliness compared to their external counterparts. The use of internal antennas eliminates the need for additional external components, reducing the overall environmental impact of the jammer. This is particularly important in today’s world, where sustainability and eco-consciousness are increasingly valued.
In conclusion, Signal Blockers with built-in antennas offer several advantages over those with external antennas. Their superior aesthetics make them more suitable for environments where discretion is crucial, such as examination halls. Additionally, the use of high-plastic materials in their construction ensures improved safety by minimizing the risk of overheating. Lastly, the elimination of external components enhances their environmental friendliness. As technology continues to advance, it is essential to consider these advantages when selecting Signal Blockers for various applications.
