Rohde & Schwarz unveiled the new ADD557SR direction finding and monitoring antenna in mid-February, with the new capability able to operate across a wide range of frequencies and detect obscured emissions.

According to the company, the new direction finding and monitoring system was designed to operate between 20 MHz and 6GHz across both vertical and horizontal polarisations, forming an “ideal” integration with the company’s DDF550 wideband direction finders and R&S DDF5GTS high-speed scanning direction finder.
Deployable across both stationary and mobile applications, the antenna can reportedly be used across the land, air and sea domains while identifying the direction of multiple sources on the same frequency, including concealed spot signals.
“Our new R&S ADD557SR multi-channel direction finding and monitoring antenna system has several unique selling propositions” Frank Mayer, vice president spectrum monitoring, Rohde & Schwarz said.
“It increases the performance of entire monitoring stations.”
In addition to direction finding, the ADD557SR is integrated with an additional antenna system that can concurrently concentrate on signals or diminish radio noise and can be switched to passive VHF and UHF operations to minimise cluttered emissions.
The R&S ADD557SR can be upgraded to super-resolution with the R&S DDF5GTS high-speed scanner.
The announcement comes shortly after Rohde & Schwarz confirmed its new agreement with the German Navy to equip the new NH90 Multi-Role Frigate Helicopter (MRFH) with software defined airborne radios for secure communications.
Under the agreement, Rohde & Schwarz will equip the German Navy’s 31 MRF helicopters with the company’s SOVERON airborne radios, with each helicopter fitted with three VHF/UHF transceivers and spares. Each of the radios is embedded with COMSEC.
Currently, the MRF helicopters are in use by the German Navy to undertake close-range protection operations, anti-surface and anti-submarine warfare missions as well as search and rescue taskings.
The radio equipment utilises the same encryption algorithms that are standardised across the NATO militaries and are specially designed for the maritime domain. A spokesperson from the company explained the transceiver’s interfaces enable external devices or external decryption devices to be integrated, while guarding the naval distress frequency.
