The Sennheiser A 5000-CP UHF Circular Passive Antenna is a passive antenna that provides an optimum solution for both transmitting and receiving RF signals throughout the UHF spectrum. Installations have demonstrated that the circular polarization of this antenna minimises variations in signal strength and almost eliminates multipath problems, a primary cause of dropouts. The gain of this antenna over the entire UHF band is superior to common `off the shelf' antennas. The wideband design (450-960MHz) of the A 5000-CP allows it to accommodate antenna distribution systems for either wireless monitors or wireless microphones across multiple frequency ranges, offering maximum flexibility when designing complex RF systems.
