Key facts

  • Wide frequency range
  • Reception of linear, dual-linear and circular polarization
  • Collapsible for easy transport
  • Use of active feeds to compensate cable loss possible
  • Manual or remote controlled operation possible

Designed for detecting RF signals and measuring field strength

The R&S®AC008 has a 90 cm special reflector with a broadband feed arranged near its focus and a device for positioning in two axes. For orientation with respect to incoming waves, the R&S®AC008 has a manual positioning device to adjust the antenna in the azimuth plane and in the elevation plane. This permits the antenna to be positioned for both terrestrial targets and geostationary satellites. Thanks to the unique feed support design, the antenna can be assembled and disassembled in a few seconds.

Features & benefits

Wide frequency range

Wide frequency coverage with a single antenna system

The R&S®AC008 covers the wide frequency range from 0.85 GHz to 26.5 GHz, saving time and space in setting up system operation compared to a multiple antenna arrangement.

For linear, dual-linear and circular polarization

Reception without limitation

The R&S®AC008 offers the choice of a series of antenna feeds. Depending on the selection, the antenna system can receive either linearly polarized signals, left-hand circularly polarized signals or right-hand polarized signals. Feeds are even available to support vertical polarization and horizontal polarization simultaneously. Operators can choose the best fit for their application.

Collapsible for easy transport

Supports semi-mobile application

The R&S®AC008 can be quickly mounted and demounted. One of the struts on the feed tripod mount is simply removed. When demounted, the system and the tripod stand can easily be stored in the trunk of a passenger car, simplifying use in semi-mobile applications.

Active feeds possible to compensate cable loss 

Increased system sensitivity

Cable attenuation can be significant in high frequency applications. Depending on the required cable length between the R&S®AC008 and the used receiver or signal analyzer, this might reduce system sensitivity. Feeds are available with switchable preamplifiers to compensate.

Manual or remote controlled operation possible

Manually directing the R&S®AC008 towards the signal source is sufficient for most applications. In some cases, the direction needs to be continuously or frequently changed. The manual system alignment can prove uncomfortable. An optional remote controlled rotator is available. A PC application with an easy to use GUI is also available for setting a new direction.
