Before purchasing a jammer, one should consider a few important factors:

5 Antenna Handheld 3G 4G All Frequency Mobile Phone Jammer

1) The band frequencies.

The right frequencies to choose depend on the devices to be jammed. In order to prevent a cell phone from being able to get reception, one should have the use of cell phone jammers, which block cellular frequencies, hence GSM,2G, 3G and 4G LTE for the latest Smartphones. In case you don´t know the frequencies on which the mobile phone transmits, the only thing left for you to do is to find out its technical specifications on the internet or somewhere else. Otherwise, you can always buy a frequency meter, which will show the specific transmitting frequency.

2) The jamming range.

Effective radius range is the jamming distances. The actual jamming distance will be varied depending on the signal strength and the use location and if full charges, etc.

3) The cooling system of the device.

Do not use the jammer when it is charging, or it will burn the jammer as it has no built-in fan, which may break the jammer. Moreover, the potential overheating of a jammer results in a reduction of its performance, apart from being detrimental to its internal components.
