Overview Key facts The R&S® HE600 Active Omnidirectional Receiving Antenna is designed as a monitoring antenna for vertical polarization in the frequency range 20 MHz to 8 GHz.

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.

Antennas HF – VHF / UHF – SHF Edition 2020 / 2021 - Catalog

Monitoring antennas for mobile and stationary use, providing complete coverage of the frequency range from 900 Hz to 40 GHz.

The R&S®EM200 digital compact monitoring receiver is a cost-efficient and optimized solution for remote controlled spectrum monitoring and geolocation. It detects, analyzes, demodulates and locates emissions from 8 kHz to 8 GHz.

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.
