Description

The A 5000-CP antenna has RF performance characteristics that are extremely desirable for usage in the UHF broadcast band, both as transmit and receive device. Actual installations have demonstrated that the circular polarization of this antenna minimizes variations in signal strength and almost completely eliminates multipath problems, a primary cause of ‘hits’ or nulls. The gain of this antenna over the entire UHF band is superior to the common ‘off the shelf’ antennas. The A 5000-CP’s extreme broadband capability provides the freedom to utilize just one antenna model anywhere in the UHF spectrum. Because of its unique 3 dimensional radiation pattern, the antenna can be mounted above the talent or venue, oriented with the antenna element facing down. With the main lobe (maximum gain) of the antenna pointing downward to the desired source, this arrangement has the advantage of greatly reduced sensitivity for potentially interfering signals arriving horizontally

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.
