How to Choose the Best 4g Signal Blocker

Posted on 26th Jul 2016 @ 9:46 AM

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

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.

To block the latest 4G mobile phone signals in the market, now more and more 4g mobile phone jammers have been invented and they are now well welcomed by people who need to cut off the signals of the 4G to gain peaceful condition. And here this 5 Antenna Handheld 3G 4G All Frequency Mobile Phone Jammer is one of the best 4G mobile phone jammers that can block both the 4G(LTE) and 4G(Wimax) signals. There are several advantages for this jammer.

Firstly, it not only jams the 4G LTE and 4G Wimax signals, it also blocks CDMA, GSM, DCS, 3G signals. This is really the most perfect and powerful jamming device by now.

Secondly, you can choose the frequency band you want to block. If you do not want to block one or two frequency bands you can just close them, keep others open. And at the same time the cell phone jammer can still work as well to jamming other frequency bands signals.

More importantly, it can be used in the car with a car charger which gives you more convenience. Besides it owns cooling fan, so the working temperature of it won’t be high. If so no matter in hot summer and cold winter it can works as well.

Are you attracted? If you are looking for a jamming device like this, do not hesitate, just take action to buy this perfect portable cell phone jammer.
