Pluggable antenna modules
Five different antenna modules from 8.3 kHz to 8 GHz with partial overlap are available. They can be plugged into the antenna handle to enable reception of vertically or horizontally polarized signals. The type of module and its orientation are detected by the antenna handle making it possible to automatically display field-strength values on the connected receiver based on stored antenna factor data.
Ease of use and control
The R&SHE400 features to trigger and toggle buttons directly on the antenna handle, allowing users to perform all necessary controls including receiver-configurable trigger actions. Its lightweight makes operation fatigue-free. In conjunction with the removable armrest, even long-term surveillance tasks in the field do not stress the user.
Geolocation and triangulation
The integrated electronic compass delivers exact azimuth and elevation data. Together with the sensitive GPS- and Glonass-capable receiver in the antenna handle, precise location accuracy is provided by triangulation.
Sensitivity and dynamic range
The built-in low-noise amplifier (LNA) is enabled or disabled with a toggle button directly on the antenna handle. It ensures optimum sensitivity in active mode but also offers improved dynamic range when switched to passive mode, where it is bypassed. The LNA as well as all other components in the antenna are supplied by the connected receiver via the cable set, thus eliminating the need for batteries inside the R&SHE400.
