This RF Venue bundle includes one COMBINE4™ IEM Transmitter Antenna Combiner, one CP Architectural Antenna for IEMs, and one RG8X25 25-foot coaxial cable. This is a complete system with components engineered to work together to combine up to four IEM transmitters of any brand into a single CP Architectural Antenna. The COMBINE4 provides DC power to up to four IEM transmitters to reduce cable clutter and wall warts. IEM transmitter combination is important for multi-channel systems to minimize intermodulation products arising from multiple adjacent antennas interfering with one another. COMBINE4 has a maximum input power of 100mW. Available in white (COMB4CP-ARC) or black (COMB4CP-ARCB).
