Sennheiser A5000 CP Antenna System

At NAB 2006 this week, Sennheiser introduced the A5000 CP passive antenna, a solution for both transmitting and receiving RF signals throughout the UHF spectrum. The wideband design (450-960MHz) of the A5000 CP allows it to accommodate antenna distribution systems for either wireless monitors or wireless microphones across multiple frequency ranges, offering maximum flexibility when designing complicated RF systems.

The gain of this antenna over the entire UHF band is superior to the common "off the shelf" antennas. Actual installations have demonstrated that the circular polarization minimizes variations in signal strength and almost completely eliminates multi-path problems. The A5000 CP's unique lobe-less polar pattern, coupled with its wideband functionality, makes it an ideal front-end for wireless systems utilizing multiple parts of the UHF spectrum.

Due to its unique three-dimensional radiation pattern, the antenna can be mounted above the talent or venue, as well as oriented with the antenna element facing down. With the main lobe (maximum gain) of the antenna pointing downwards, the energy is focused toward the desired source resulting in greatly reduced sensitivity for potentially interfering signals.

The A5000 CP greatly enhances the performance of a non-diversity system and makes the diversity system virtually bulletproof. When used side by side with any other antenna, the signal stability of the A5000 CP is instantly recognizable. Robust housing is designed for "real-world" applications. Unit can be stand or wall mounted.
