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.
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.
Key Features:
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
