Sennheiser A 5000-CP – Passive Circularly Polarized UHF Antenna

Product Overview

The Sennheiser A 5000-CP is a passive circularly polarized UHF antenna built for reliable RF coverage in professional wireless microphone and in-ear monitoring systems. Its circular polarization minimizes signal-strength variation and virtually eliminates the multipath reflections that cause dropouts, making it a dependable remote antenna for wireless microphones in demanding commercial AV and live-production deployments. A wideband 450–960 MHz design lets a single antenna model serve multiple frequency ranges across an integrated RF distribution system.

Product Description

The A 5000-CP is a directional (helical) antenna engineered for both transmitting and receiving across the UHF spectrum, giving AV system designers a single, flexible building block for complex RF infrastructure. Because it is passive, it requires no external power and can be paired with active antenna boosters or splitters when longer cable runs demand additional gain. The circular polarization pattern maintains a consistent signal as performers or presenters move through a space, a key advantage for houses of worship, auditoriums, and large conference rooms where line-of-sight is not guaranteed.

Gain across the full UHF band exceeds that of common off-the-shelf antennas, extending usable range for wireless microphone and wireless monitoring receivers. The antenna accepts standard 3/8" or 5/8" threaded mounts for tripod or truss placement, so integrators can position it for optimal coverage during installation. Its wideband coverage makes it a practical standard across a facility running multiple Sennheiser wireless platforms. For multi-channel monitoring rigs, pair it with the Sennheiser AC 3200-II antenna combiner, or feed receivers for a Sennheiser EW IEM G4 wireless monitoring system.

Technical Specifications

Frequently Asked Questions

What wireless systems is the A 5000-CP compatible with?
It works with UHF wireless microphone and in-ear monitoring systems operating within the 450–960 MHz range, including Sennheiser evolution wireless and 2000-series platforms.

Does the antenna require power?
No. The A 5000-CP is passive. For long coaxial runs, add an active antenna booster or splitter to compensate for cable loss.

How does circular polarization improve reliability?
Circular polarization keeps signal strength more consistent as transmitters move and reduces multipath reflections, which are a primary cause of RF dropouts.

How is it mounted during installation?
It uses a standard 3/8" or 5/8" threaded connection compatible with common microphone/antenna tripods and truss mounts.

Can I use it for both wireless mics and in-ear monitors?
Yes. The wideband design supports both transmit and receive applications, so it can serve mic receivers or feed a monitoring transmitter within the same RF plan.

What warranty applies?
