There are many multi-frequency jammers that can deal with few frequency bands at once. Despite their universal usage, not all of them are capable of blocking separate frequencies from all possible ones without jamming the other ones at the same time. Still there are some exclusive models like switched signal jammer which jammed frequencies might be turned on and off separately.
And there is more! The most advanced desktop jammer of these days is called adjustable desktop jammer. Every single jammed band among those you would select to install on that jammer can be controlled by its own control knob that allows you to adjust the jamming power of the frequency band or turn it off completely.
Thus you can choose to purchase either more simple jammers or more complex ones with switches for every jammed band.
