Does the jammer block multiple frequency bands at the same time?

When the electronic interference industry was just beginning to develop, signal gps jammer were used to block a single frequency band. Later, with the development of these useful jamming devices, more and more frequency bands were added to the list, and new jammers were developed and manufactured. They have very few antennas, so they can only block very few signals at a time.

The most popular combination of blocking frequency ranges is a combination of frequencies in a certain frequency band. For example, GSM frequencies (such as GSM850, GSM900, GSM1800, and GSM1900) are no longer blocked individually, but are blocked together by signal jammers. However, more and more frequencies are added to the interference list and new types of jammers are created, such as WiFi / Bluetooth / 3G / GSM jammers, 4G / LoJack / XM radio jammers, and even multi-frequency desktop jammers .

As you can see, modern technology is not set in stone and will continue to evolve to provide us with impressive new features, so the jammer is constantly updated and iterated.
