About RF Venue

The CP Beam™ Antenna is a lightweight, circularly polarized antenna that doesn’t drop out and is designed to ensure a consistent signal with in-ear monitors (IEMs), wireless microphone systems, and other UHF communication devices. 

The CP Beam is easy to set up and transport – fitting in a 3RU rack drawer and weighing just 2.5 lbs – and compresses for easy storage (see the before and after compression). Unlike other bulky helical antennas that require flight cases, the CP Beam is quickly deployed and stowed.

Why do IEMs drop-out anyway?

Provides constant signal regardless of IEM receiver position

Can collapse to fit in a rack drawer for transport

Key Features Image

Not buried in a rack – better signal with line of sight to IEMs

Focused beam signal – for better reception compared to omnidirectional

Helical antennas are overwhelmingly the antenna of choice for IEMs due to their circular polarization. This removes the greatest risk of dropouts, as many IEM belt packs are limited to a single whip antenna and changing orientation as performers move around a stage.

The benefits of a helical antenna (CP Beam) vs. a whip antenna: 

  • Provides constant signal regardless of IEM receiver position
  • Not buried in a rack – better signal with line of sight to IEMs 
  • Focused beam signal – for better reception compared to omnidirectional 

To use, disconnect straps and extend CP Beam. Connect coaxial cable (not included) to receiver, transmitter, or antenna combiner. Provides up to 9 dB of antenna gain. Mounts to ¼"-20, ⅜"-16 or ⅝"-27 threads.

 

Reduce the impact of dropouts due to the changing position of the IEM bodypack

For IEM systems, getting a good signal to the bodypack receiver is essential. One barrier to great reception is that many belt-pack receivers don’t support diversity reception--which is to say they have only a single antenna. This makes these receivers much more likely to encounter dropouts and multi-path fades than the dual antenna diversity systems common in microphones and higher end IEMs. The belt-pack is also in motion, and can change orientation depending on body position. Plus, the pack sits beside or behind the talent, requiring the signal to pass through or alongside the performer's body, which is nontransparent for RF energy.

Product combinations

Using a combiner is especially important for transmitting devices like IEMs.  Without it, multiple IEM transmitters in a rack, each with their own whip antenna transmitting on top of each other can be a disaster for your system.  These antenna farms create noise and intermod problems that can wreak havoc not only on IEM performance but neighboring wireless microphones as well.  The solution is a clean rack with an IEM combiner and helical antenna.

Most common questions asked:

What is the CP BEAM designed for?

The CP Beam provides all of the benefits of helical antennas in a lightweight, durable, folding form-factor.

Read more
What type of equipment will the CP Beam work with?

The CP Beam antenna is compatible with UHF wireless microphones, UHF in-ear monitors, UHF IFBs and UHF and 900 MHz intercoms.

Read more
How many CP BEAMS are needed per receiver?

Some of the benefits of circular polarization may be achieved by using only one CP Beam per diversity receiver, while leaving the stock whip/dipole attached to the other diversity branch.

Read more
Can I use the CP Beam with IEMs?

Yes. The CP Beam is perfectly suited for any brand UHF broadcast band (470-698 MHz) in-ear monitor that accepts external antennas at the transmitter.

Read more
What are the best practices for IEM systems?

For the best performance and easiest setup, when using multiple channels of IEM they should be connected to a combiner and then retransmitted via a single helical antenna using the lowest gain setting that reliably works on your transmitters.
