RF Venue CPB – CP Beam Directional Circularly Polarized UHF Antenna

Product Overview

The RF Venue CPB is a directional, circularly polarized helical UHF antenna designed for in-ear monitor and wireless microphone applications requiring focused, dropout-free signal delivery. Its helical design transmits and receives signal across all polarization planes simultaneously, making it well suited for IEM transmit applications where performer body pack receivers may be oriented in any direction. Lightweight and collapsible, the CP Beam is equally at home in a permanent installation or as part of a touring production rig.

Product Description

The CP Beam (CPB) addresses one of the most common causes of IEM and wireless microphone dropout: polarization mismatch. Traditional linearly polarized antennas only effectively transmit or receive signal in one plane (typically vertical). When a performer moves and the receiver's antenna changes orientation, signal strength drops. The CP Beam's helical circular polarization transmits across all planes simultaneously, maintaining signal integrity regardless of body pack orientation.

The CP Beam is directional, with a focused beam pattern that concentrates RF energy toward the performance area. This directional gain provides better signal strength at distance compared to omnidirectional alternatives, making the CP Beam a strong choice for larger stages, auditoriums, and any venue where antenna-to-performer distance is a concern. For IEM applications, RF Venue recommends pairing the CP Beam with the COMBINE4 (4-channel) or COMBINE6HDR (6-channel) combiner to consolidate multiple IEM transmitter feeds to a single CP Beam antenna. The CP Beam includes an N-BNC adapter and a stand-mount bracket, and collapses for transport or storage. For a complete IEM pack including the COMBINE4 and cable, see the COMB4CPB bundle.

The CP Beam is compatible with all major UHF wireless microphone and IEM systems in the 400–800 MHz range. It is also suitable for other UHF communication devices requiring directional circularly polarized antenna performance.

Key Features

• Circular Polarization — Helical design transmits and receives across all polarization planes, eliminating dropouts caused by body pack orientation changes.

• Lightweight and Collapsible — Folds for transport; fits in a rack drawer or equipment case for touring use.
• IEM and Wireless Mic Compatible — Suitable for IEM transmit applications (paired with a combiner) and wireless microphone receive applications.
• N-BNC Adapter Included — Ships with an N-BNC adapter for connection to BNC-terminated coaxial cable runs.
• Stand-Mount Bracket Included — Mounts on a standard microphone stand or antenna bracket for optimal positioning.
• Universal Frequency Range — Operates across 400–800 MHz covering all major UHF IEM and wireless microphone bands.

Typical Applications

Suitable for:

• IEM transmit antenna for houses of worship with multiple IEM channels (paired with COMBINE4 or COMBINE6HDR)
• Auditorium and performing arts center IEM and wireless microphone systems
• Live event and touring productions requiring directional antenna coverage

Frequently Asked Questions

Can the CP Beam be used for wireless microphone receive as well as IEM transmit?

Yes. The CP Beam is suitable for both IEM transmit and wireless microphone receive applications. Its circular polarization and directional gain benefit both use cases.

How many IEM channels can be fed through a single CP Beam?

RF Venue recommends a maximum of eight IEM transmitters through a single combiner-antenna system. For best performance, combine no more than four channels with the COMBINE4 into a single CP Beam, or up to six channels with the COMBINE6HDR.

What is the difference between the CP Beam and the CP Architectural antenna?

Both are circularly polarized UHF antennas. The CP Beam is a directional helical antenna designed for stand-mounting and touring use. The CP Architectural antenna is designed for permanent wall or ceiling mounting with a slim, paintable enclosure for architectural integration.

Does the CP Beam come with a cable?

The CP Beam includes an N-BNC adapter and stand-mount bracket but does not include a coaxial cable. For a complete IEM pack including a 25-foot cable, see the COMB4CPB bundle.
