Kaltman Creations IWxCPA1

Circular Polarized Antenna

The new IWxCPA antenna uses advanced circular polarization technology which produces a ‘drop-out free’ transmitter and receiver combination that is never out of phase. This technology, along with the antenna’s directional attributes, helps to guarantee as reliable of an RF signal link as possible.

Traditional paddle and rod antennas used for wireless microphones are either horizontally or vertically polarized (usually vertically, as a mic is usually vertically oriented). When a microphone transmitting antenna changes its orientation in reference to the receiving antenna - as wireless mic’s and belt pack transmitters always do - the phase relationship changes. The new IWxCPA antenna uses advanced circular polarization technology which produces a ‘drop-out free’ transmitter and receiver combination that is never out of phase. The antenna incorporates directional, Circular Polarization (CP) technology for both receiving and transmitting pro-audio wireless applications. This antenna will reduce interference, reduce drop outs, help eliminate ‘swishing’ noise artifacts, improve RF signal to to noise, and enhance reception of signals propagated through and around objects.

The antenna design is unique in many ways, the most obvious being its low-visibility flat panel sign. Unlike paddle and helical antennas that point into the performance area and, therefore, expose their large sides to the audience, the theatre black IWxCPA panel faces the performance area leaving only a 1.3 inch edge visible to the audience.
