Signal jammer for sale   are a type of equipment specifically used to shield wireless signals. Their main function is to prevent terrorists or other criminals from using wireless remote control bombs, walkie-talkies, mobile phones, drones and other equipment to carry out terrorist attacks or other criminal activities. In order to ensure that the signal jammer can perfectly complete the tasks assigned by superiors when shielding wireless signals, and in the absence of casualties, the requirements for the jammer to shield the wireless signals of the hand are extremely high. So, what factors can affect the shielding effect of the signal jammer? Transmission power of the RF module: The greater the transmission power of the RF module, the greater the shielding range. Therefore, when selecting an RF module, a high-power RF module should be given priority. However, if the bandwidth of the signal transmitted by a single module is too wide, it will also affect the shielding effect. Therefor...
