Before buying a jammer, you should consider the following important factors:
1) Band frequency.
The correct frequency selected depends on the device to be shielded. To prevent cell phone reception, people should use cell phone jammers to block cellular frequencies, so GSM, 2G, 3G and 4G LTE are used in new smart phones. If you don’t know the frequency of the mobile phone’s transmission, the only thing you have to do is to find its technical specifications on the Internet or elsewhere. Otherwise, you can buy a frequency meter at any time and it will display a specific transmit frequency.
2) Interference range.
The effective shielding radius is the interference distance. The actual interference distance will vary depending on the signal strength, location of use, and charging conditions.
3) The cooling system of the equipment.
Do not use the shield when charging, otherwise it will burn the shield because it does not have a built-in fan, which may damage the shield. In addition, the potential overheating of the shield is not only harmful to its internal components, but also causes its performance to decrease.
In order to shield the new 4G mobile phone signals on the market, more and more 4G mobile phone jammers have been invented, and they are now popular with people who need to cut off the 4G signal to obtain peace. And this 5-antenna handheld 3G 4G full-band mobile phone jammer is one of the good 4G mobile phone jammers, which can block 4G (LTE) and 4G (Wimax) signals. This shield has several advantages.
First, it can not only block 4G LTE and 4G Wimax signals, but also block CDMA, GSM, DCS, and 3G signals. This is currently the perfect and powerful shielding device.
Secondly, you can select the frequency band to be blocked. If you don’t want to block one or two bands, you can turn them off and leave the other bands open. At the same time, mobile phone jammers can still interfere with signals in other frequency bands.
More importantly, it can use the car charger in the car to provide you with more convenience. In addition to having a cooling fan, its operating temperature is not high. If so, it will work no matter in the hot summer and cold winter.
Are you attracted? If you are looking for such an interference device, please don't hesitate, just take action to buy this perfect portable phone jammer.
