What is a "Universal Jammer"? The Most Authoritative Explanation.

What is a jammer and how does it work?

To put it simply, a Jammer is, fundamentally, a signal blocking device, which transmits synchronized radio waves on the same frequency range of the device that one needs to blur, therefore preventing devices from transmitting data in the chosen area. The blurred frequencies. The typical jamming coverage.

Is there such a thing as a Universal Frequency Jammer?

First of all, just to make things clear, there are no such things as universal jammers, capable of blocking all of the existing frequencies. The only device that comes close to such a product is what we, usually, call a Bomb Jammer. But, there are several issues that have to be taken into account before handling such potentially dangerous devices.

Which signal jammer is best for 360° inhibition?

For an all-around 360° view inhibition, you’d better opt for a signal jammer with omnidirectional antennas. Pro: Easy to install. Con: if what you aim to achieve is a disruption in a specific spot, just ahead of you, almost half of the output power will be wasted to cover 180° range behind the point of interest.

What types of devices can be blocked by a simple jammer?

Let’s take a glance at the most common devices that make use of the above-mentioned frequencies and how we can block them by resorting to a simple jammer: VHF and UHF frequencies are used by the following devices: Bugs, LoJack locators, radio controls, TV antennas, etc.
