      About the Product

      Product Setup

      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. The CP Beam provides all of the benefits of helical antennas in a lightweight, durable, folding form-factor. Helical or “multi-polarized” antennas provide higher gain due to their coverage pattern (narrow beam width), and superior protection against interference due to the circular polarization of the antenna element.

      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. However, where budget and space allows, two CP Beams should be used for exceptional range improvement and dropout protection.

      What are the best practices for IEM systems?

      Helical antennas are overwhelmingly the antenna of choice for IEM transmission because the circular motion of the RF field emitted distributes the signal through all possible polarization angles. This removes the greatest risk of dropouts, as most IEM belt packs are limited to a single whip antenna. For the best performance and easiest setup, when using multiple channels of IEM they should be connected to a combiner and then transmitted via a single helical antenna using the lowest gain setting that reliably works on your transmitters. The use of multiple transmitting antennas on multiple transmitters almost always results in signal degradation. We recommend feeding no more than eight transmitters into a single combiner system as exceeding that number rapidly increases the probability of IM (intermodulation) interference and results in the likely reduction of possible open channels for both your mics and ears.
