No signal blocker, no defect

Frequency: Which to choose?

Choosing the right frequency depends on the device to be interfered with. In order to prevent a phone from receiving a signal, there needs to be a phone blocker that blocks cellular frequencies and therefore blocks GSM, 2G, 3G, and 4G LTE for the latest smartphones. If you don't know how often your phone is transmitting, all you have to do is find its technical specifications on the Internet or elsewhere. Otherwise, you can always purchase a frequency meter, which will display the specific emission frequency.

So what is the recommended power output?

First, it's important that you know what kind of interference you need to create around a particular area. For 360° panoramic suppression, it is best to choose a signal blocker with an omnidirectional antenna.

Pros: Easy to install.

Cons: If your goal is to jam at a specific location in front of you, almost half of the output power will be wasted covering 180° behind the point of interest.

On the other hand, if you need to interfere with frequency transmission at a certain location, you should choose a directional antenna.

Advantages: The full power of the blocker will be concentrated at the selected location.

Disadvantages: The antenna is large and heavy to install.

Once you have chosen the antenna type, you have to give it your full attention and never underestimate the so-called signal strength. The assumption is that the stronger the signal, the smaller the range of our device. No signal jammers are not defective. They're all defective.

Therefore, it is recommended that you first check the signal reception in the area where you have decided to install the frequency blocker.

Only after considering all of the above factors can you choose the signal blocker that best suits your needs. Always keep in mind that the higher the wattage, the greater the distance they can cover.

How long will it work?

It all depends on how the device is built.

The heat dissipation of the interference device is the most important factor. Too much heat can cause the cell phone jammer itself to malfunction, and loss of strength is the first consequence you'll notice, followed by damage to all its internal components.

Our selection includes equipment with a different range of fans and cooling systems, which will ensure that you never exceed a specific warning temperature, thanks to the top materials used for product assembly.
