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.
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.
