Do not use the jammer when it is too hot, otherwise it will reduce the life

Frequency band

Depends on the frequency signal equipment to be blocked. To prevent the phone from being able to receive the signal, a phone jammer must be used, which will block the phone frequency and therefore GSM, 2G, 3G and 4G LTE and the latest smartphones. If you don’t know the transmission frequency of your phone, you can find it elsewhere on the Internet or in its technical specifications. Otherwise, you can buy a frequency counter at any time to display a specific transmission frequency.

Is the interference distance of the effective radius. The actual distance will vary based on the strength of the interference signal and similar locations of use and a fully charged battery.

Cooling system equipment.

Do not use the jammer when it is loaded, otherwise it will burn the 4G jammer, because there is no built-in fan, it will interfere with the jammer. In addition, potential overheating can result in degraded jammer performance and damage to its internal components.

In order to prevent the last signal from interfering with the mobile 4G mobile market, more and more mobile phone shields 4G have been invented. We recommend focusing on mobile 6 full series 3G 4G antenna interference that can stop 4G (LTE) and 4G (Wimax) mobile phones. This is one of the best interference signals for 4G phones. This interference has several advantages.

First, it only blocks 4G LTE and Wimax 4G signals. It also blocks CDMA, GSM, DCS, 3G, LOJACK signals. This is currently the most complete and powerful interference device.

Second, you can choose to block the tape. If you don’t want to block one or two bands, you can close them while leaving the other bands open. At the same time, the mobile phone jammer can still operate to block signals in other frequency bands, and is equipped with an LED screen, we can observe the frequency change at any time, and also has a camouflage appearance, which is very suitable for military applications.

Most importantly, it can be used in a car charger for your convenience. In addition, it has a cooling fan, so its operating temperature is lower. If so, it works both in hot summers and cold winters.

If you want to attract such interference devices, then you are right, don’t hesitate to buy this perfect mobile phone jammer now.
