Reduce Clutter

RF Venue's COMBINE4™ Package (RF-COMB4CPB) bundles the COMBINE4™ IEM Transmitter and the CP Beam™ High Gain Folding Helical Antenna. The COMBINE4™ combines signals from up to four in-ear monitor transmitters into a single CP Beam™ antenna, reducing clutter, signal interference, and lowering the probability of intermodulation artifacts. Any brand IEM may be used, and DC power is provided to up to four IEM transmitters to reduce cable clutter and wall warts. The exceptionally portable and resilient CP Beam™, increases range and improves reception and provides 9dB of directional gain from its circularly polarized beam.


  • Combines Signals From Up To Four In-Ear Monitor Transmitters
  • 470-960 MHz Frequency Range
  • 470–698 MHz Operating Frequency
  • Provides DC Power To Up To Four IEM Transmitters
  • Minimize Intermodulation Products

In 2011, RF Venue began marketing a range of patented wireless products that fall into three categories: Antennas (transmitting and capturing signals), Distribution (moving those signals around), and Software (visualizing the RF spectrum using a combination of hardware and software). The company continues to develop a range of products within the commercial sound equipment industry to reduce signal dropouts and interference for all brands of wireless audio equipment.
