An antenna for (almost) all purposes Sennheiser presents the A 5000-CP circularly polarized helical antenna Wedemark/Paris, May 2006 High gain, virtually no multipath problems and superb RF performance over the entire UHF broadcast band the A 5000-CP passive helical antenna that Sennheiser is presenting at the AES is the optimum antenna solution for even the most demanding projects and difficult transmission conditions. The circularly polarized A 5000-CP can be used as both a transmit and receive device, making it the ideal antenna for wireless monitoring systems and radio microphones. Unlike conventional helical antennas, most of which have a much narrower bandwidth, the A 5000-CP covers the entire UHF range from 450 to 960 MHz. This flexibility makes setting up even the most complex RF transmission systems much easier. The antenna minimizes variations in signal strength and almost completely eliminates multipath problems. The gain of the A 5000-CP over the entire UHF band is superior to that of conventional antennas. The A 5000-CP features an opening angle of 40 and considerably improves the performance of Non-Diversity systems. The sturdy radome is in black acrylic, while the base plate is made of anodized aluminum. The antenna can be mounted on a stand, on the wall or, using an additionally available Matthews pin, on a lighting grid. Visit Sennheiser at the AES, Paris Expo, Hall 5.2, Stand No. 1813.

antenna

Polarized
Sennheiser launches its circularly polarized antenna designed for wireless monitoring and wireless microphone systems.

Announcement

The A 5000 CP passive antenna provides the optimum solution for both transmitting and receiving RF signals throughout the UHF spectrum. Its wideband design (450-960 MHz) allows it to accommodate antenna distribution systems for wireless monitors and wireless microphones across multiple frequency ranges, offering maximum flexibility when designing complicated RF systems. When used as a transmitting antenna, the unique circular polar pattern of the A 5000 CP dramatically reduces dropouts in non-diversity wireless monitor bodypack receivers.

Fearures and Benefits

Highly directional, passive performance Optimum solution for transmitting and receiving RF signals throughout the UHF spectrum Wideband design (450-960 MHz) works across multiple frequency ranges Ideal for wireless monitoring and microphone systems Unique circularly polarized design reduces drop-outs caused by multi-path problems Robust housing designed for real-world applications Designed for convenient stand or wall mounting
