Atlanta, GA (October 10, 2012)—Kaltman Creations LLC has introduced the Invisible Waves IWxCPA antenna to improve reception for wireless microphones.

The IWxCPA incorporates directional “circular polarization” (CP) technology for both receiving and transmitting pro-audio wireless applications. According to Kaltman, it is designed to help reduce interference, reduce drop outs, eliminate ‘swishing’ noise artifacts, improve RF signal to noise and enhance the reception of signals propagated through and around objects.

The new IWxCPA antenna uses advanced circular polarization technology, which reportedly produces a ‘drop-out free’ transmitter and receiver combination that is never out of phase.

According to Kaltman Creations LLC President Mark Kaltman, “The IWxCPA antenna strengthens one of the weaker links in the RF chain - the transmitter to receiver link. Interestingly, in the pro-audio wireless world, there is little consideration given to the profound effect polarization can have on the performance of our wireless gear.”

The antenna has a low-visibility flat panel design. Unlike paddle and helical antennas that point into the performance area, the theatre black IWxCPA panel faces the performance area leaving only a 1.3 inch edge visible to the audience.

The antennas are passive with a 60 degree beam-width and the pattern is circular polarized in the 470MHz to 960MHz range. For use with in-ear-monitor transmitters, IWxCPA has a maximum input power rating of 3 Watts. The 10 inch x 10 inch x 1.3 inch, 2.5lbs antennas include a swivel mic stand mounting capability (optional truss mount available) and are painted theatre black with a 50 Ohm low-loss BNC connection.
