Sennheiser A 5000 CP
The Sennheiser A5000CP Circulary Polarized Antenna is designed for use with wireless microphones and monitor systems to achieve higher radio-frequency (RF) signal at long range. The A5000CP operates on a wide-band UHF frequency of 450 - 960MHz, making it universal and capable of operating with most UHF wireless systems.
The Circularly Polarized dramatically reduces interference and drop-outs when used with non-diversity wireless systems. The highly directional antenna features a 40 degree beam angle, minimizing intermodulation and interference while increasing range.
