Sennheiser A 5000-CP Passive Directional Circularly Polarized Antenna

Directional circularly polarized antenna for reliable wireless reception in challenging RF environments

The Sennheiser A 5000-CP is a passive directional antenna with circular polarization, designed for professional wireless microphone and in-ear monitoring systems. Circular polarization provides more consistent RF performance than linearly polarized antennas when transmitter orientation changes during a performance, such as when a performer tilts, rotates, or moves a handheld transmitter or bodypack at different angles on stage.

The directional pattern focuses the antenna's sensitivity toward the performance area while rejecting interference from behind and to the sides. Combined with circular polarization, this makes the A 5000-CP one of the most reliable antenna options for challenging RF environments including large stages, outdoor festivals, and venues with significant multipath reflections from walls, ceilings, and stage structures.

Key Features

• Directional pattern focused on the performance area
• Circular polarization for consistent reception regardless of transmitter orientation
• Passive design requires no external power
• Wideband UHF coverage for multi-frequency wireless deployments
• Wall and stand mountable for flexible placement
• Compatible with Sennheiser wireless receivers and IEM transmitters via BNC

Professional Applications

Commonly deployed in church, house of worship, and professional AV environments.

• Large venue and arena wireless microphone antenna systems
• Outdoor festivals and events with challenging RF environments
• Theater installations requiring reliable coverage of the stage area
• Broadcast facilities with multipath reflections and RF congestion

Frequently Asked Questions

What advantage does circular polarization provide over linear?

Linearly polarized antennas lose signal when the transmitter antenna rotates out of alignment. Circularly polarized antennas maintain consistent reception regardless of transmitter orientation, which is important when performers move freely with handheld and bodypack transmitters.

Can the A 5000-CP be used for in-ear monitor transmitting?

Yes. The A 5000-CP works for both receiving (wireless microphones) and transmitting (in-ear monitors), providing directional, circularly polarized coverage in both roles.

Related Equipment and Workflow Compatibility

The A 5000-CP connects via BNC to any Sennheiser wireless receiver or IEM transmitter. It is commonly deployed in antenna distribution systems alongside Sennheiser antenna splitters, boosters, and coaxial cables for large-scale wireless deployments.

Why Professionals Use This Type of Product

• Circular polarization eliminates signal loss from transmitter rotation
• Directional pattern rejects interference from outside the performance area
• Passive design is reliable with no power requirements
• Essential for large venues, festivals, and multipath-heavy environments
