This desktop powerful blocker for phone and Wi-Fi jamming is designed for high-density communication environments. It has high penetration and stability, and can continuously suppress common wireless signals such as mobile phones, WiFi, GPS, etc. within a range of 10-50 meters.
Equipped with 12 external high-gain antennas, it supports free combination and customization of frequency bands and adapts to frequency standards in different countries or regions. If necessary, please contact customer service to provide requirements (such as only blocking 4G/5G/WiFi, retaining remote control signals, etc.).
The device is easy to install and plug and play. It supports flat desktop or wall-mounted installation to meet the layout requirements of different usage scenarios.
The body has three sets of high-speed cooling fans built in, supplemented by honeycomb heat dissipation holes and aluminum fin heat conduction structure to achieve “active + passive” dual-effect thermal management. Even if 12 frequency bands are turned on at the same time and output continuously for a long time, the device still maintains stable operation.

Related science about the effect of power on jamming effect:
Q: Is power important?
A: Very important. Many 5W machines have an actual power of less than 1W. So, it must be the actual power. Remember, low-power machines cannot penetrate walls. Only when the single-channel power of this jammer reaches 4-5W can it effectively penetrate medium obstacles such as walls and glass for stable interference.
Q: Why can’t my 4G jammer block the 4G signal?
A: Generally speaking, if there is a base station nearby, it is basically useless to buy a low-power machine because the signal strength of the base station is too strong. It is recommended to buy a medium-power mobile phone signal blocker to be effective.
Q: What if the base station is on the roof of my house?
A: Even the best jammer can’t beat it unless you buy a super high-power machine.
Q: Can I buy a cheap device to stop my child from playing games in another room?
A: It’s hard to do. Generally, the price of a cell jammers that penetrates the wall is not cheap, at least several hundred dollars.
