HE600 Active Omnidirectional Receiving Antenna
In this application note the fundamental working principles of active antennas are asserted and it is described what makes them different compared to passive antennas. Furthermore the important parameters relating to active antennas are explained and typical system applications are discussed - including a comparison with passive antenna solutions and a chapter explicitly dealing with radio monitoring in the HF frequency range.

Protective measures can only be taken after a threat is detected. To effectively counter the threat, early warning is critical – every second counts. When R&S®ARDRONIS detects commercial drone activity, it automatically classifies the type of drone signal, determines the direction of the drone and its pilot, and (on command) disrupts the radio control link to prevent the drone from reaching its target.
Intelligence, surveillance and reconnaissance from a single source
For more than a century, mankind has been increasing its use of the frequency spectrum. Authorities, who have been managing this spectrum, consequently require enhanced and extended spectrum monitoring capabilities.
R&S®NESTOR is a Windows based software for analyzing cellular networks over the air interface. It is widely deployed by law enforcement agencies, intelligence services, armed forces and regulatory authorities. R&S®NESTOR is used together with Rohde & Schwarz mobile network scanners and QualiPoc smartphones, which offer the most advanced technology worldwide. The software supports all relevant applications that public authorities and security organizations need to gather information about cellular networks. R&S®NESTOR is used in vehicles, trains, aircraft, drones, on ships and on foot.
