Rohde & Schwarz HE400CEL – Cellular Antenna Module, 700 MHz to 2500 MHz

Rohde & Schwarz HE400CEL – Cellular Antenna Module, 700 MHz to 2500 MHz

The R&SHE400 handheld directional antenna is used to locate transmitters and interference sources. Bearings are found by manually pointing the antenna in the direction where the signal is strongest. The antenna is optimized to be used with the R&SPR100 portable receiver or the R&S FSH and the R&S Spectrum Rider FPH handheld spectrum analyzers.

It consists of an antenna handle, a receiver-customized cable set, and different antenna modules that can easily be attached using a locking ring. Five different antenna modules are available, allowing the reception of vertically or horizontally polarized signals. The type of module and its orientation is detected by the antenna handle. A built-in low-noise amplifier (LNA) can be activated to increase system sensitivity. In passive mode, the amplifier is bypassed and the antenna can also be used in the vicinity of strong transmitters.

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. The integrated trigger button can be used to externally trigger a receiver-configurable action.

Benefits and key features

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.
