The cell phone signal jammer should protect the signal received by the mobile phone from the base station and be attenuated when encountering obstacles. If it is a block reinforced concrete wall, the attenuation after penetration is very important. If it is made of plasterboard, the attenuation must be lower. Basically, if it's glass or wood, there won't be much attenuation. Today Saiyue Newsletter tells you how to connect to your cell phone. The signal jammer is getting stronger.

Step 6: Put the finished fan-shaped iron shell on the antenna of Texin portable gsm jammer. As shown in the figure, many antennas can be made of 2-3 identical iron shells.
