NOCTRA SA 21-Antenna Portable RF Signal Jammer
21-antenna multi-band RF interference equipment
The NOCTRA SA 21-antenna model is a portable radio-frequency jammer. Its intended function is to create interference on configured radio bands; it is not a passive detector, spectrum analyser or a device that measures communication quality.
How it works
A jammer transmits interfering radio signals that can disrupt reception within the frequencies covered by its installed modules. Antenna count does not establish universal coverage or a guaranteed protected area. Results depend on the actual configuration, signal conditions and environment.
